He is cold-hearted enough to use cruel methods and show no mercy even to family members if it serves his purpose.

Influenced by this, he loves cute things and clothes, and usually spends his time cross-dressing. He is very fond of Byakuya because Byakuya honestly praises him as "cute."

He watches over Hakuo's earnest efforts to be masculine with a smile, sometimes jokingly asking, "Do you think it's strange to see someone as tall and masculine-framed as me dressed like this?" Because he has experienced mockery himself, he empathizes with Hakuo's feelings and offers subtle comfort.
