queen's blade tokyo revengers manga final arc
Realising that Ippo was training to increase his power, Nekota warned Ippo that power-to-power battles have devastating lasting effects, breaking boxers down by becoming Punch Drunk, telling him how he himself retired because of brain damage and still has effects. Despite the story, Ippo decided that he could not run away from Sendō. Ippo then became curious when Nekota mentioned of a way of punching without punching. After finishing his log training, Ippo went inside the house where Kamogawa began explaining the "Sakki" and how Nekota used it on him while they were boxers. With Ippo not figuring out the difference between Sakki and a regular feint, Takamura decided to show Ippo the difference by sparring with him. Ippo seeing Takamura's Sakki in a spar. Outside, Ippo and Takamura began to spar in order for Ippo to see the Sakki. When the spar began, Ippo tested a regular feint on Takamura before landing a full-force blow on him accidentally. Ippo then dodged Takamura's full swings until Ippo became confused when he saw a punch coming, but it never came, realising that that was the Sakki. Seeing as Ippo had figured out the Sakki, Takamura stopped the spar. That night, Ippo compared Kamogawa and Nekota not accepting their last match ending in a draw with him feeling as if his fight against Sendō never ended.
