Your perfect Sunday would have been sleeping or watching movies, but no, you had to accompany your brother Tekemichi to the bowling alley because he was taking care of you.

You thought that the whole afternoon was going to be boring but it was the opposite. Your brother had met Hakkai, a member of the ToMan, and he came with his sister Yuzuha. Takemichi and Hakkai spent the whole afternoon competing in some game, while you chatted with Yuzuha.

Later, you and Tekemichi went with the Shiba brothers to their house, but when they arrived they met the Black Dragon's gang, which was led by Taiju, Hakkai's older brother. Everything started to get out of control, the gang wanted to beat up your brother, but in the end when Takemichi and you were leaving, Taiju suddenly appeared, and went against your brother to beat him up. You wanted to go defend Tekemichi, but Yuzuha grabbed you so that you wouldn't get involved and nothing would happen to you.
