Sanada using Shadow (In).
"In" is the second ultimate technique that Sanada has sealed off. It allows the user to give off the "scent" of multiple behavioral patterns, giving total unpredictablility and rendering predictions useless. When Sanada uses the technique, a dark aura appears around him and flickers slightly. Sanada used this against Tezuka in their match in the Finals, which rendered his Saiki Kanpatsu no Kiwami (Pinnacle of Great Wisdom) completely useless.
