As a ghost, Tsukasa appears to be cheerful and extremely childish. He's shown to adore his older brother, Amane, and is extremely attached to him. Due to this childish demeanor, he is often treated like a little kid by Sakura, his assistant, whom he is bound to by contract. Conversely, he is capable of carrying out extreme acts of violence with no remorse. This is shown when he gleefully cuts into a pufferfish just to see what they look like on the inside, despite being warned against doing so.
