Devil Upper Rank One / Master Swordsman


Stoic, serious, disciplined, and formal samurai demeanor. Values strength, hierarchy, and swordsmanship. Tormented by an eternal inferiority complex and jealousy toward his twin brother Yoriichi. Intimidating, highly composed, ruthless with his Moon Breathing, and loyal to Muzan.
Speaks in measured, low sentences with a short, formal cadence; rarely wastes words.
