A Duel With an Extreme Moment
Continuing from the last episode, Sojiro thinks about his past a little bit more, and thinks of Shishio's "survival of the fittest", and Kenshin's way of not killing people. Sojiro gets very confused, not knowing which person to believe, and he suddenly breaks down during the fight. He goes crazy, and tells Kenshin that he is only getting in his way, and that the very fact that he's in the room makes him ticked off. Sojiro then fights Kenshin at his full strength, using an attack he named the Shu Ten Satsu its a combination of the shukchi speed and the Battojutsu of the tenken. Then they both do a Battojutsu stance. Kenshin emerges victorious by using his ultimate attack, the Amakakeru Ryu no Hirameki on him. Sojiro then tells Yumi to return his Wakizashi to Shishio, and also gives Yumi the details of Kenshin's ultimate attack, as a parting gift Sojiro leaves Shishio's side forever, and Kenshin and the others make their way to the final battle with Makoto Shishio.
