After failing to save the world for the 39th time, 自分 once again regresses. By some coincidence, 自分 encounters 相手 & requests a duel to the death in order to improve his skill for the next iterations [Sword of Patience]: 自分 calmly deflects all [Harmful Intent] from 相手, silently evading & leading the fight to his path to victory, awating for a moment's mistake to finally strike w/ fatal force.
