[DeepL Translation - needs review] Introduction of the first volume: The most powerful assassin, Nagi Taira, became unconscious after protecting his younger sister from a bullet.
He has a special constitution that allows him to regain consciousness for a short period of time when he is hit with the "intent to kill".
In order to achieve full awakening, Nagi begins his "rehabilitation" in a modified wheelchair against his strongest enemies today!
