Chachakaka comes off as a happy-go-lucky person, a façade that masks a much more dangerous side, owing to the fact she is an assassin. According to Shiori, she likes to be alone, and she sleeps by herself. Chachakaka is also very mischievous and often likes to pull harmless pranks. She has the same common verbal tic found among most Kaka and talks in the third person.
