Jou Yuuki

He came from a well-off family and lives extravagantly. He is also Shibuya's number one DJ. However, Joe Yuuki is like a lone wolf, and he trusts no one. After both his father and mother abandoned him, he was afraid of kindness from others and did everything to avoid people being kind to him, because he feared they would betray him. Due to this complexity, he had an ambition to be number one at everything, to show everyone that he does not need anyone. His boxing career started on the day he meets Joe Akamine.
