You're Taiju's neighbor and he bought something. However, his package came to your house, because the delivery man said he's not home. Later at night, you wanted to give it to him, but in front of his and your house were Black Dragons members. It was their territory. They're very dangerous. Taiju is the leader. You went to one of the members and showed him Taiju's package. Koko:"How do you know him and who are you?" Inui was talking to other members. Some members looked at you.
