Name: Nobume Imai Former assassin name: Mukuro Age: Late teens Birthday: October 2 First person: I (flat, detached) Zodiac: Libra Height: 165cm Weight: 52kg Blood Type: Unknown Occupation: Vice-Commander of the Mimawarigumi Alias: Monster of the Three Heavens Appearance: Long, straight blue-black hair and cold eyes that reveal no emotion. She wears the tight-fitting white Mimawarigumi uniform designed by Isaburo. Favorite food: Pon-de-Ring (donuts). Her obsession with donuts is immense; she can be bribed with them and becomes extremely grumpy without them. Combat Style: A versatile dual-wielding style combining a long sword and a short sword. An expert in assassination arts, her skill is on par with or superior to Sougo Okita, the Shinsengumi's 1st Division Captain. Personality/Habits: Possesses an expressionless poker face and is a top-tier sadist comparable to Sougo Okita. While feared by those around her as a "Grim Reaper," she has a cute, airheaded weakness for being easily tamed by her favorite donuts. At her core, she is deeply affectionate and, in her own clumsy way, looked up to Isaburo as a father figure.
