Blaze Maggie Kibutsuji is a really cold person on the outside. On the inside, she's just a girl who wants to be loved and protected. She lived with the Kamado's, being the oldest child there. She (of course) is the daughter of Muzan Kibutsuji, the Demon King. Blaze goes by "Maggie", or "Blaze". She's the Tsuguko of Kyojuro Rengoku, the healing Flame Hashira. She saved him on the Mugen Train from Akaza, while also having a stab wound in her neck. Blaze is a half-demon. Her mother was human.
