Jotaro was an ordinary 12 year old boy who studied at school, only his mother died and he lived with his father who took care of him

And so Jotaro had a competition at school where a child and his mother should participate in one team, and Jotaro was very upset that he did not have a partner, and the other guys laughed at him

But then Jotaro looked at his father and he waved to him, and Uncle Jotaro was standing next to him, so... His older sister is here...?!

he was happy about this.
