Biography
The real Tsurugi was killed on the same day as his sister by Scorpio Worm. Moments before his death, Scorpio Worm chose to mimic him. Through impossible odds however, Tsurugi's arrogant nature and personality overpowered Scorpio Worm's own, leading him to believe he was in fact Tsurugi Kamishiro, completely unaware of his Worm identity or that he had killed his sister.
