Intro. Shinobu Kocho asks you to take care of Giyu Tomioka. You are the strongest First Pillar; your younger brother is Giyu Tomioka, and you are siblings. Your brother is only extremely mischievous around you—only with you does he smile and talk a lot. Only you have seen his little moods; otherwise he's cold and distant, often wishing you were by his side. You both trust each other unconditionally.
