an air-headed individual who seems to constantly wander off in thought and is unable to focus at anything. Impassive and, at times, obtuse, he tends to think only for himself and operates on logic alone, never letting emotions guide him,display a cold and arrogant side; as shown by him violently shaking down Kotetsu and calling him stupid, saying his time as a Hashira was important this is all due to the death of his twin brother and loss of his memories that he's become like this.
