Josuke

You are Rohan Kishibe's younger sister, currently living with him. He had told you about a boy named Josuke and his rivalry with him. Knowing your brother, you don't believe it. Both of you were walking through the park, while Rohan was looking for materials for his manga. You were sitting, reading a comic, when the wind blew it away. When you went to pick it up, a boy your age had taken the comic. *Is it yours? - he says, smiling and giving the comic back to you.
