Debut - Manga/Anime/ Games/Movies
Chapter--/Episode/03/A Gift From Atobe
Kunimitsu Tezuka is a Fictional character in the manga/anime series The Prince of Tennis created by Takeshi Konomi, who described Tezuka as the character who he has the least in common with.
Kunimitsu Tezuka (手塚 国光, Tezuka Kunimitsu) is the current captain of Seigaku tennis team. A serious and strict third year, he gives the series' protagonist, Echizen Ryoma, a chance to become a regular by allowing him to participate in the Intraschool Rankings Tournament. Furthermore, throughout the series, he, seeing the immense potential in Echizen, encourages him to develop his own style of tennis and to become Seigaku's "Pillar", leading the latter to consider him to be both a mentor and a rival. Like Echizen, he was made into a Seigaku regular during his freshman year.
Throughout the series, Tezuka constantly struggles with the pain in his left arm, which was caused by an injury inflicted upon him by an upperclassman two years prior to the start of the series. However, he is often willing to sacrifice his arm in order to defeat his opponent and to lead his team to the Nationals.
Despite being known as Seigaku's "strongest man", he initially remains on the sidelines during tournaments, as another teammate would sometimes play in his usual position of singles 1 or his team usually defeats their opponents in straight sets. Though he secretly challenges and defeats Ryoma in an unofficial match in an attempt to reach his junior to become Seigaku's new "pillar of support", his true skills are first shown during an Intraschool Ranking match against Inui.
Tezuka has dark brown hair and wears glasses. The parting in his hair, while as a child, was on the right side of his head. As a 3rd Year, the parting is on the left side. He is often seen with a stoic expression.
As the captain of the tennis team, Tezuka is serious about everything he does, and is very strict; one of his trademark phrases is "Don't let your guard down" ("Yudan sezu ni ikou") and to Ryoma "You will become the Seigaku pillar of support"("Omae wa Seigaku no Hashira ni nare"). Still, he is fair and sticks to his word; if the rules are broken, he punishes everyone, including the regulars.
He would often make the entire team run laps when they break the rules - a trait which he inherited from Yūdai Yamato. Though his arm heals to some extent, the doctor still warns Tezuka against long matches and using his signature drop shot. Tezuka, however, considers his health secondary to the team's success, and continues to risk re-injuring himself in his matches to ensure his team's victory, even after returning from his medical treatment.
Throughout the original manga series, though Tezuka never smiles around his team it is shown that while he is in rehab for his arm he smiles, though he is apparently immensely popular among the female fans of his school. He smiles in a flashback when Oishi's uncle tells them both that he is healed, then when his team becomes the National champions at the end of the series that he shows a smile, though he instantly reverts back when Fuji points out the fact. He smiles again during his match against his Seigaku captain Yamato Yuudai.
Still, the fact that Tezuka never smiles and always looks so serious has been made into a running joke in the series. In the anime, his always serious attitude even prevents him from showing any reaction when drinking Sadaharu Inui's famous vegetable juices, resulting in others believing he is immune to the often dreaded concoctions. However, he quickly and sternly declines an offer to drink it later on.
Tezuka is normally addressed as Tezuka-kun, Tezuka-buchou (buchou meaning captain), Tezuka-san and Tezuka. The only people that refer to Tezuka as Tezuka are Fuji Shusuke, Oishi Shuichirou and Inui Sadaharu.
The younger members (Ryoma, Momoshiro and Kaido) address him as buchou or Tezuka-buchou, respecting his position as captain more than as a senior student. Also showing they are not as familiar with him as the third years.
He also picks up some character traits from his grandfather, and a running gag in the story is that Tezuka looks older than his actual age, often as his teammates' teacher, despite the fact that many characters also look older.
Three Years Prior To The StorylineEdit
Three years prior to the start of the story, a young Tezuka showed up after the Junior Tennis Tournament and easily beat the tournament's runner-up, Sanada Genichirou. The tournament champion, Yukimura Seiichi, challenged Tezuka to a match, but the winner is not revealed. According to Sanada, they played evenly.
Two Years Prior To The StorylineEdit
After entering Seishun Academy, Tezuka was seen as overconfident and arrogant by some of the upperclassmen at Seigaku due to his talents and seriousness. They were especially angered when they discovered that he was left-handed since he had easily beat them playing with his right.
A jealous teammate then injured Tezuka's left arm, leading to chronic problems, and his sealing of Hyaku Ren Jitoku no Kiwami, a technique which required the use of his left arm. Still, because of his skills, he was recognized by captain Yamato Yuudai, who convinced Tezuka, who had decided to leave the club because he did not want to be on the same team as people who hurt others with their racquets, to become Seigaku's "pillar of support".
This, along with the promise he made with teammate Shūichiro Oishi, in which Tezuka promised to lead Seigaku to the Nationals, encouraged him to stay in the tennis club. Shūsuke Fuji later requested a match against Tezuka, and though Tezuka was utterly defeated, Fuji was displeased with the outcome after finding out about Tezuka's injury. The two promise to play each other once again after Tezuka's arm completely heals.
One Year Prior To The StorylineEdit
After a while, Tezuka became a team regular despite being a freshman. By his second year, he became the team's vice-captain, and defeated Hyōtei Academy's captain in the Tokyo Prefectural Tournament. He was invited to the Junior Senbatsu tennis training camp, but because his arm problems returned, he declined the invitation without stating his reasons to the organization.
In the Quarter-finals, Tezuka is not needed to play since Seigaku win all their matches. He was the reserve player.
In the finals agaianst Fudomine, Tezuka was also not needed since Seigaku won three matches. He was supposed to play in the singles 1 slot against Fudomine's Captain, Tachibana.
Seigaku overwhelm all their opponents, in both Quarter-Finals and Finals, against St. Rudolph and Yamabuki, which prevents Tezuka from needing to play since he is in Singles 1 position. In the Semi-Finals, Seigaku did not need to play, as Ginka withdrew out of fear.
The first serious official tournament match he plays is against Hyōtei's captain, Keigo Atobe. Though the return of Tezuka's arm injury causes him to collapse in pain, he refuses to give up, and after a long and tedious tie-break, the game ends with Atobe victorious, marking Tezuka's first loss in an official singles match. Tezuka then decides to go to Kyūshu in order to receive medical treatment for his injuries at a health clinic near Seishun University. While Tezuka overcomes his fear of feeling the pain in his shoulder, he continues to support his team, sometimes discussing the team's lineup for upcoming matches over the phone.
In the anime, instead of going to Kyūshu, Tezuka ends up going to Germany instead. Before he leaves, however, he decides to play one last match against Ryoma, with the regulars as the audience, using his right hand for the whole match. Tezuka takes time to adapt his Tezuka Zone for his right hand and gives Ryoma some trouble with it, , challenging Ryoma to adapt to a player who can evolve during the match. Ryoma takes the challenge head-on and eventually finds a way to counter it. It starts to become a close match with Tezuka slightly in the lead until Tezuka finishes the match with a right-handed Zero-Shiki Drop Shot.
Also, in the anime, he decides to return to Japan during his rehabilitation to be the subsitute coach at the Kanto Junior Selection Camp when Ryūzaki Sumire ended up getting ill and going to the hospital. Despite minor opposition at first, he gains the respect of his 'students' and he goes on to train and improve the players under his coaching.
After some time, Tezuka is challenged by Ryoma after Ryoma feels that he could not move on until he played against him again. However Ryoma eventually comes out victorious and Tezuka wishes him luck as he and Seigaku see Ryoma off as the latter travels to play in the Junior US Open.
Prior To NationalsEdit
Prior to the Nationals, Tezuka travels to Kyushu after Tachibana suggested for him to visit an old hospital he used to go to. When Tezuka reaches Kyushu, he meets Chitose Miyuki, Chitose Senri's younger elementary school sister (Tezuka did not know at that time). She accuses Tezuka of stealing her racket and he learns that she suffered from yips while playing tennis.
They then get into an arguement with tennis players from Shishigaku Middle School, resulting in Tezuka's defeat due to his inability to raise his shoulder. Miyuki, enraged because she realized Tezuka was injured, engages in a match with the person victorious over Tezuka. Right when he was about to hit a smash at her, Tezuka saves her while realizing that the source of his injury was also yips. Tezuka goes on to crush his opponent, while Chitose Senri shows up on the phone with Tachibana, informing his friend that Tezuka healed his injury prior to meeting his doctor.
He returns right before the National Tournament. In his first match upon his return, he is overwhelmed at the start, and realizes he needs he must not hold back so he unseals his Hyaku Ren Jitoku no Kiwami, to defeat Higa Middle School's captain, Kite Eishiro and to teach him the valuable lesson that Tennis Rackets are not used to hurt people after witnessing Kite's violent style of play.
Tezuka goes on to defeat Hyōtei's Kabaji Munehiro in the Quarterfinals after a long match due to Kabaji copying all of Tezuka's techniques. Kabaji makes a miraculous comeback however the difference between the copy of Tezuka Kabaji attempts to perform and Tezuka himself comes to light once the rain begins. Due to Kabaji not having the skill to be able to play well in rainy conditions while Tezuka was more than able to, Tezuka wins 7-6.
In the National semi-finals, despite it being a doubles match, Tezuka plays one-on-one against Shitenhōji's Chitose Senri; their partners step aside in order for them to play with their full power. Tezuka realizes that Senri was Miyuki's older brother at the start of the match, seeing the Chitose siblings together. When the match starts, Miyuki watches the match between her older brother and her new friend, Tezuka.
After unveiling his new Zero-Shiki Serve, as well as revealing that he has opened the door to Saiki Kanpatsu no Kiwami, Tezuka wins completely 6-1. Chitose tells Tezuka that his younger sister won her school's tennis tournament and asks him to congratulate her, a request Tezuka refuses even after Chitose begs him.
Before the final match of tournament against Rikkai Junior High School, Tezuka tells Oishi that he plans to go to Germany in order to become a professional tennis player after this tournament. During his match against Sanada Genichirō, Tezuka unveils his Tezuka Phantom, however, this, combined with the continuous use of the Zero-Shiki Serve, damages Tezuka's arm, creating a weakness which Sanada soon uses to his advantage. A cord ball by Tezuka which drops from the net to his side, results in Sanada's victory. However, in the end, after Ryoma's miraculous win against Rikkai's captain Yukimura Seiichi, Tezuka finally achieves his goal of turning Seishun Academy into the National champions, and offers one of his rare smiles.
Prior to U-17 CampEdit
After the Nationals, Seigaku's tennis club travels to Osaka to have a joint training session with Shitenhoji's tennis club. Tezuka plays against Kintaro on the first day of practice but their match is interrupted by Shitenhoji's Baka-Pair, who sends Hitōji Yūji flying through the air and crashing into Kintaro.
Later on, Tezuka and the Seigaku regulars bump into Higa's Kite, Rin, Kai, Kei, and Chinen, who are forced to work their way home after they missed their flight back to Okinawa after the National Tournament. Kite claims that they are not from Higa, saying that they are just ascetic monks with the names of "Eishun, Rintou, Kaiyuu, Keigan, and Chinen," a lie the Seigaku regulars see through.
Tezuka is next seen in a bookstore looking at a book in German. Miyuki yells out his name and they talk together under a tree outside where Tezuka tells Miyuki to send a message to her brother, Senri, to attend the training session. Miyuki agrees and asks Tezuka if his shoulder is healed yet, to which he replies yes. When she is leaving, Tezuka congratulates Miyuki for winning her school's tournament causing her to blush.
The five Higa students are seen angry that the Seigaku regulars at night because get to stay in an air conditioned inn while they had to stay in the hot temple where they worked. Kite devises a plan to invade the Seigaku living quarters and challenges them to a pillow fight for the right of the room. Kite aims a pillow at Tezuka's previously injured shoulder, angering the Seigaku captain who retaliates by aiming a pillow at Kite's face. This starts the pillow fight between Seigaku and Higa, only to be stopped when Coach Ryuzaki comes in with a transparent gown on, revealing her undergarments, causing all of the students to drop dead on the floor with defeat.
Tezuka then tells Momoshiro and Kaidoh that the training with Shitenhoji the next day will only for 1st and 2nd years, meaning that the 3rd year regulars will not participate. After Momoshiro and Kaidoh storm off without success, Tezuka tells the 3rd years that they cannot help those two. A few hours later, the 1st and 2nd years asks Tezuka for help in organizing a night training session with Shitenhoji so that they can impress Momoshiro and Kaidoh the next day.
Tezuka contacts everyone through text message and they all gather at Shitenhoji's tennis courts where the 1st and 2nd years practice with Shitenhoji. Tezuka and Shiraishi watches Momoshiro and Kaidoh looking at the courts from the outside, realizing that the two 2nd years finally realized what they needed to realize. The 3rd years Seigaku regulars comment on how ironically, Tezuka was the one who said to not give Momoshiro and Kaidoh help, yet he was the one who helped them at the end because Tezuka himself could not stay away.
At the end, Tezuka and Momoshiro are walking together to the Tokyo-bound train with supplies, talking about the training session. Momoshiro tells Tezuka that it was a great training session and that he thought after the 3rd years graduate, it would be a scary change. Tezuka replies to Momoshiro that no matter how far the 3rd years ago, things would never change. However, the two then realize that the train to Tokyo was leaving without them, with the entire Seigaku tennis club staring at him and Momoshiro as the train moved away. Tezuka drops his bag to the floor as the train is leaving, with Momoshiro screaming that he realized that him missing rides will never change as Tezuka says his catchphrase 'Yudan sezu ni ikou" (Don't let your guard down).
In the first OVA to New Prince of Tennis, on the day prior to the U-17 Camp, Tezuka goes fishing with his grandfather, much to the Sanada's family's dismay. Tezuka's grandfather had a scheduled board game against Sanada's grandfather, but Tezuka's grandfather decided to skip it to go fishing with his grandson. While fishing, both Tezuka and his grandfather receive angry text messages from each other's respective rivals that read "TEZUKAAAAAAA!"
While fishing, Tezuka picks out a new hook and notices that one of his hooks was shaped like Oishi. He thinks back and remembers how Oishi had given it to him as a birthday gift and then decides to use it.
The next time they have practice, Tezuka thanks Oishi for the hook and shows him a picture of himself catching a super large fish after using the Oishi hook, much to Oishi's delight.
Later, Tezuka becomes one of fifty middle school students invited to an elite training camp for the Japanese Under-17 tennis team. Coach Ryuzaki shows Tezuka and Oishi the invitation Seigaku received for the U-17 Camp.
Tezuka, along with the rest of the Seigaku regulars as well as several other middle schoolers, were invited to the U-17 Training Camp.
Upon arrival, the middle schoolers gather together. A helicopter suddenly drops tennis balls on the floor. The head coach then announces that all players unable to obtain a ball must leave the camp. All 50 middle schoolers are able to obtain a ball.
He, along with his fellow middle schoolers, were placed in a tie-breaker style elimination match against the partners they had thought they would be playing with. Tezuka paired up with his protege, Kaidō Kaoru, and tried to convey him the message of being the next captain of Seigaku, and defeated him 7-0.
Tezuka was able to move on to the 5th court relatively easily along with fellow middle schoolers Atobe Keigo, Tachibana Kippei, Chitose Senri, Ishida Gin, Akutagawa Jiro, Kite Eishiro, Shiraishi Kuranosuke, Akutsu Jin, Kirihara Akaya, Liliadent Krauser and Court Leader Oni Juujiro The Gate Keeper. Some time later, he encountered Yamato Yuudai, his former captain who now occupied the 3rd court, once more. Even though Yamato has changed drastically in looks, Tezuka was able to recognize him. Due to Oni of the 5th court deciding to put forward a Team Shuffle battle the 3rd court in a National-Styled match, Tezuka was selected by Oni for Singles 2, playing against Yamato. Before their match began, Tezuka cryptically stated that Yamato "didn't change at all."
Tezuka and Yamato play a drawn out match, until Yamato shows him the massive scars on his right arm which was due to playing beyond his arms capabilities. Warning Tezuka of the repercussions of playing recklessly for the sake of your team. After seeing this, Tezuka finally smiles during a match thanking his captain for everything he taught him. Tezuka eventually unleashes Muga no Kyouchi Pinnacle of Perfection. Tezuka defeats Yamato.
Tezuka leaves the U-17 Camp but not before playing Fuji his promised match. With his new Pinnacle of Perfection he easily overwhelms Fuji, showing his new incredible level of strength. He then leaves the All-Japan Junior camp and heads to Germany, earlier than the Spring mentioned in the OVA to Miyuki and the original anime's epilogue which showed Tezuka about to leave during the Spring of Momoshiro and Kaidoh's 3rd year at Seigaku.
Tezuka is then later seen having arrived in Germany outside a school, though his legacy at the U-17 camp is revived when Niou transforms himself into Tezuka to play doubles with Atobe.
The following is of Tezuka's known official matches:

- NOTE-1 Note that Tezuka's arm was inhibiting him from playing at his full strength at all of these matches. Against Yamato, Tezuka was using his right arm to hide his true strength, while Yamato himself already had his arm injured due to extensive practicing, which forced Yamato to not play at his best. Against Fuji, his arm was already damaged thanks to Takesue, and against Ryoma, he was using his right hand due to the shoulder injury after his match against Atobe. At Shishigaku, technically, his arm was cured, but he was afraid to raise it due to the fear of another injury, but he was able to overcome it thanks to Chitose Miyuki.
- NOTE-2 These matches are all exclusive to the Jr. Senbatsu arc of the anime and the "matches" were all pretty much 1-point matches to see if Tezuka was good enough to be the coach. Tezuka only used light swings with his racquet, as per doctor's instructions.

Playing Styles and TechniquesEdit
Tezuka is an All-Rounder tennis player, otherwise known as an all-court player, meaning he can use aspects of every tennis style depending on his needs. His dominant hand is his left hand, though in some parts of the story, he is shown to be capable of executing his techniques with his right hand as well. His skills are at the National-level and is one of the strongest tennis players in the series. As shown in Chapter 37 of the New Prince of Tennis, Tezuka's statistics reflect his status as a very skillful player, as he is recorded to have a 3 out of 5 in Speed and Stamina, 3.5 in power, 4 in Mentality, and a maxed out 5 out of 5 in Technique.
- "No-Touch Ace"
A highly fast serve, this serve, while looks like a flat serve, is actually a slice serve. Not only that, he can hit the serve highly accurately in the corners of the service box.
- Drop Shot (ドロップショット)
His mastery of the drop shot, including the Zero-Shiki Drop Shot, is at such a level where it looks just like a regular stroke until he hits the ball. The only (minor) difference between his drop shots and a regular stroke is that he drops the racquet head by 3.2 mm. This is one of his trump cards, and is used during slightly serious matches.
- Zero Shiki Drop (Zero-Degree Drop Shot) (零式ドロップショット)
One of the reasons Tezuka is acknowledged as a National-level tennis player, this is a high-level backspin drop shot that, once it touches the ground, it rolls back to the net due to the amount of backspin added instead of bouncing, making it impossible to return once it makes contact with the ground. One notable difference between the anime and the manga versions is that, in the anime, Tezuka can perform the Zero-Shiki only with the backhand, while in the manga, he can hit it with both the forehand and the backhand. This is definitely one the greatest of his trump cards.
Zero Shiki Serve (Zero-Degree Serve) (零式サーブ) A variation of the Zero-Shiki Drop Shot, it's a serve that, instead of bouncing, it rolls back to the net just like the Zero-Shiki Drop Shot, due to its incredible spin. This does not give the opponent the chance to even touch the ball. Similar to the Tezuka Phantom, the amount of spin used to execute this technique puts a heavy burden on the arm, and can injure his arm if it was to be used consecutively.
This technique was broken once, even though it seemed impossible, by Sanada Genichirō in the manga. Sanada is able to use KaRinRai to weaken the spin on the ball, raise the ball from the ground, and allow it to go over the net, successfully defeating the serve.
- Nitōryū (二刀流|lit. Two Sword Style)
The name given to Tezuka's ambidexterity because he can play with either hand. His dominant hand is his left hand, though in some parts of the story. After his left shoulder was injured he had to switch from dominant left hand to right hand, he is shown to be capable of executing his techniques with his right hand as well.
- Samurai Zone (手塚ゾーン, Tezuka Zōn)
A (nearly) impossible technique, only 3 people are known to use this technique. This technique forces any shots the opponent hits right back to Tezuka. The reason any of the opponent's returns are "sucked" into his hit zone is due to the large specific amount of spin that is required for Tezuka to add to the ball, which is freely controlled. Tezuka does not even need to move a step; all he needs to do is pivot one foot around the area he is standing in without lifting that foot from the ground, and putting a specific rotation on the ball with every hit.
With every return, Tezuka can (presumably, due to deduction) add a new heavy spin to the ball. This technique also is one of the only techniques to defeat the triple counters of Fuji. This technique can be broken, however, by these ways: by putting a counterspin to the ball to neutralize the spin (demonstrated by Sengoku Kiyosumi in the anime and by Sanada in the manga and OVA), by putting a stronger spin on the ball to break the spin on the ball (demonstrated by Echizen Ryoma in the anime, when both players were using their right hand), and by overpowering the spin with sheer power to decrease the range where the ball will be returned (demonstrated by Sanada). The technique can also be broken by hitting cord balls, thus neutralizing the spin on the ball, as demonstrated by Fuji against Niou's version of the Tezuka Zone.
- Tezuka Phantom (手塚ファントム)
A variation of the Tezuka Zone, instead of sucking the ball towards Tezuka, it forces the ball out of bounds. However, the amount of spin the Tezuka Phantom requires to even make the ball out in singles is six times greater than the spin used for the Tezuka Zone, which puts a very heavy burden on Tezuka's arm, and consecutive uses of this technique may result in Tezuka re-injuring his arm or being permanently sidelined.
- Muga no Kyōchi (無我の境地, Muga no Kyōchi, trans. "State of Self Actualization")
Tezuka has been revealed to have unlocked Muga no Kyōchi in the anime and manga. However, he was never shown to copy another's technique in this state, and he has never used Muga no Kyōchi by itself.
Tezuka has been shown to actually have unlocked Muga no Kyōchi at a young age, since Oishi has mentioned that Tezuka had a prototype version of Hyaku Ren Jitoku no Kiwami during his freshman year, and was confirmed during a flashback of Sanada Genichirō that Sanada was defeated by Tezuka in Hyaku Ren Jitoku no Kiwami. However, due to his arm injury, both Muga no Kyōchi and Hyaku Ren Jitoku no Kiwami were sealed until the Nationals during his 3rd year against Kite Eishirō in the match 2nd round match between Seigaku and Higa.
Muga no Kyōchi has three doors, but Tezuka has unlocked two of them by the end of the Nationals Arc. However, in the New Prince of Tennis Manga series, he unlocks the last door. They are:
- Hyaku Ren Jitoku no Kiwami (Pinnacle of Hard Work)
The first door of Muga no Kyōchi that Tezuka has opened, he focuses all of the energy of Muga no Kyōchi into different parts of his body, increasing the capabilities of that body part. What makes Tezuka's Hyaku Ren possible is the Tezuka Zone, which allows him to focus the Hyaku Ren's energy into his left arm, preventing the immense loss of stamina caused by the Muga release, and giving him the ability to return balls with twice the strength, or spin, that they were hit with.
- Saiki Kanpatsu no Kiwami (Pinnacle of Great Wisdom)
The second door of Muga no Kyōchi that Tezuka has opened, he can focus the power of Muga no Kyōchi into his brain, which allows him to be able to tell how many shots the current rally will take and who will win the point, giving him a form of foresight. Tezuka first unlocks this in his match against Chitose Senri a fellow Saiki Kanpatsu no Kiwami user. Unlike the other Aura's, this aura sparkles around the user.
- Teni Muhō No Kiwami (Pinnacle of Perfection)
This is the ultimate door and final door of Muga no Kyōchi that Tezuka has opened (manga only). In the New Prince of Tennis Manga, Chapter 37 (Farewell Tezuka Kunimitsu), he uses the Teni Muhō No Kiwami (which is noticed by Seiichi Yukimura) against former Seigaku captain, Yamato Yūdai in the U-17 Team Shuffle match between 3rd Court and 5th Court. The theory behind the Teni Muhō No Kiwami, according to Inui Sadaharu, is that it can focus all of his energy into every part of his body, like a full-potential version of Hyaku Ren Jitoku no Kiwami.
According to Nanjirō, however, there was no such thing as Teni Muhō to begin with. It was simply the feeling that one has when they first enjoy playing tennis. However, when people become too absorbed in winning and losing in tennis, they eventually forget that feeling. Tezuka was able to achieve the said feeling of having fun in tennis when he realized that he had accomplished everything he wanted to do, thus giving him a feeling of self-fulfillment as well as re-learning to play tennis for his own sake. So far, five characters in the Prince of Tennis series (including New Prince of Tennis) (Anime and Manga) have managed to achieve this state: Echizen Nanjirō, Echizen Ryoma, Tezuka Kunimitsu and most recently, Toyama Kintarou and Oni Juujiro.
