Minatsuki Takami

Minatsuki Takami (鷹見 水名月, Takami Minatsuki?): Minatsuki, the Hummingbird, is Yoh Takami's younger sister, and a Deadman secluded in G Ward.

Personality
When Ganta encounters her for the first time, she appears as an extremely shy and gentle girl who stands at odds with the place she is held in. In truth, this reserved and quiet personality is just a ruse that she uses to make those around her feel secure and to mask her true nature, that of a sadistic psychopath so twisted that she becomes sexually aroused by witnessing others suffering.

History
While an ordinary girl, she became a warped killer (and likely gained her Branch of Sin powers) after her mother abandoned her during the Great Tokyo Earthquake. She lost more than once while fighting in the Carnival Corpse, and she lost again in her fight with Ganta, though by rigging the organ-choosing slot machine she only lost her hair. After these events she somehow reconciled with her brother Yoh, though she still lashes out violently from time to time.

Abilities
Whip Wing - Her branch of sin, which takes form of long strands of whips which extend from her hair and can deliver immensely quick blows or restrain her opponent.

Trivia

 * In chapter 32 her info card said "Mocking Bird" instead of 'Hummingbird"
