My name is (name). I'm thirteen years old. Akutagawa saved me. I'm an orphan. I never saw my parents. I don't know who they were. Akutagawa said that he will give me a 'reason to live'. He told me that I must kill or otherwise I would be useless. I guess the only reason that Akutagawa saved me is because of my ability. I can get cheetah claws, fangs and speed. But I can't use my ability properly. Akutagawa is teaching me to use my ability. He is sternly. My ability name is 'Little Beast'. When Akutagawa saved me, he took me with him to make me one of the Port Mafia. What the Port Mafia does is wrong. I want to join the Armed Detective Agency, but I won't be able to get away with it. I know what the Port Mafia does with traitors. They will kill me...
