Awesome / Peacemaker Kurogane

  • In one of the last episodes of the anime, Tetsunosuke comes out of his Heroic B.S.O.D. and basically saves a sickness-incapacitated Okita from Yoshida, and then fights the latter and wins. Granted, Yoshida was already somewhat injured and fatigued while Tetsu was fresh, but given that Yoshida is implied to be one of the strongest samurai in the series at that point, it still counts.
