Minatsuki Takami

Minatsuki Takami, the Hummingbird, is Yō 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. This was also seemingly confirmed by her love for flowers. 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 liar (and gained her Branch of Sin powers) after her mother abandoned her during the Great Tokyo Earthquake. Her father, her brother and her lived alone from onwards. Because of her twisted personality, she manipulated Yō to think that his father was physically abusing her, often resulting in his brother beating up his father in retaliation. One day, she a faked sexual assault and Yō attacked his father once again. For reasons unknown however, Minatsuki used her powers and killed her father. Not knowing of Minatsuki's abilities, Yō held himself responsible, nevertheless she was sent to prison not long afterwards, and because of her powers, she was confined in G Ward.

Deadman arc
Minatsuki is first seen when she, Idaki Hitara, Masu and Chaplin went to meet Ganta. She still appears as a shy and vulnerable girl. She accompanies the group to go see the Penatly Game for Senji Kiyomasa, in which he was torn an eye out. During these images, she kept her smile and acted like nothing important was going on.

The next day, she was assaulted by Masu, who wanted to eat her flowers. Ganta comes out of his room and offers Masu his breakfast in exchange for the flowers. He takes Minatsuki back in her room.

Abilities
Branch of Sin: As a Deadman, Minatsuki possesses a Branch of Sin. This allows her to freely control her blood. To forcedly bring her blood out, she rips out one of her earrings, causing her ears to bleed. She got this ability when she inhaled one of the Red Diamonds during the Great Tokyo Earthquake.

Branch of Sin: Whip Wing (ウイツプ・ウイング, Uippu Uingu): Her Branch of Sin, which takes the form of long strands of whips which extend from her hair, can deliver immensely quick blows or restrain her opponent. It forms from blood coming out of her earrings and due to this, it blends in with her hair.
