Minatsuki is the younger sister of Yoh Takami, and a Deadman known as "Hummingbird" in the complex. She initially appears as a very shy, reserved little girl who cannot stand violence and her horrible past. Minatsuki soon shows that it is a ruse to lure opponents into a false sense of security. She is actually very sadistic, deriving sexual pleasure from seeing the pained looks on her victim's faces. She especially likes the look of her brother blaming himself for their father's death, though he does know the real truth. After losing to Ganta, she reconciles somewhat with both Yoh and Ganta, but still lashes out at them frequently. Her Branch of Sin is called "Whip Wing", which uses blood from her ears to create whips that can quickly strike and restrain the target. Her sadistic character comes from her experience in the earthquake. When the earthquake first hit Japan, Minatsuki was with her mother, but when she thought her mother was coming to save her instead she picked up a plant and ran, leaving Minatsuki behind until her brother saved her. That's when she became more sadistic and hating towards humanity.
