Characters
A girl with white hair who is a honey badger (ratel) hybrid. Her honey badger DNA means she does not feel fear even when facing opponents far larger, stronger and faster than herself in death matches. Her fighting strategy usually involves insulting her opponents into attacking her first, then counterattacking with lethally fast slashing cuts. She has an obvious crush on her guardian, Reiichi Shido, becoming lovestruck in his presence and immediately following any order he gives her. She treats anybody but Reiichi with mild contempt and indifference, frequently forgetting people's names even if they are opponents she has fought in the past, such as Leo. After the Killing Bites tournament, Shido orders her to assassinate Nomoto, much to her resistance.
A second year university student who was forced into a plot by several classmates to kidnap Hitomi. Following this incident he is forced by Hitomi's guardian, Reiichi Shido, to allow Hitomi to live with him as his bodyguard. In return Yuya must act as Hitomi's financial backer to allow her to take part in death matches against Hybrids belonging to the four Zaibatsu. After the battles, Hitomi attempts to assassinate him, but survives. Learning that he is officially dead, Yuya takes refuge among the hybrids and plans his revenge against Shido and the Zaibatsu. After the series' timeskip, he becomes a Crow Hybrid and starts conspiring to get his vengeance against those who betrayed him, demonstrating a more mature and resolute personality. His feelings toward Hitomi, however, are the same as before and, even though he understands that he, Inui and Kuroi may have to face her one day, he still hopes her to survive and be free from Shido's influence.
She is a Cheetah hybrid specialising in speed type attacks. She is the younger sister of Taiga and represents the Yatsubishi Zaibatsu alongside her brother Taiga. She loses the final match of the first destroyal against Ui in a very unexpected way, and since then her main purpose is to get vengeance against her for having been humiliated in that occasion.
She is a Rabbit hybrid who has never won a fight and prefers to run away from danger. After the destroyal she becomes worldwide known as the strongest hybrid ever seen, and one of the most respected member of the underground and unrecognized Killing Bites matches. For the same reason however she becomes also a puppet for the elite controlling the new hybrids community, that can force her to do whatever they want to not see her secret about how she won the destroyal publicly revealed.
He is a burly man who is a Hippopotamus Hybrid. He represents the Ishida Zaibatsu with Seira Son as his sponsor.
Eruza's older brother and a Tiger hybrid. He represents the Yatsubishi Zaibatsu and sees Yuugo as his rival.
She is an overseer of the Death Matches.
Hitomi's legal guardian who orders her to live with and protect Yuya. He frequently uses Hitomi's crush on him to make her obey his orders without question or hesitation. He uses the Death Matches as the testing grounds for his own hybrid research. After obtaining power from the four zaibatsu, he orders Nomoto's assassination and orders Hitomi to execute him, as Nomoto knew too much as well as wanting Hitomi to remove all attachments; not realizing, he would soon make an enemy out of the young man.
