|Rinko Echizen nee Takeuchi|
Her maiden name is Rinko Takeuchi. She works as an attorney, which has been her long-time dream. She met Nanjiro while playing tennis when she got hurt from saving a boy from an abusive tennis coach. Nanjiro avenged her by completely humiliating the coach in a match.
She is sweet and compliant, but quite strong-willed as well. She is a quick-witted woman and one of the few ladies who did not fall for Nanjiroh's charming personality. She found him to be brash and also rude at times, but after he saved her, Rinko's perspective changed towards him. It can be said that both Ryoga and Ryoma got their quick-wit from her.
- She likes Western food as opposed to her son, who dislikes it.
- She appears to be half a head shorter than her husband.
