Dai Moroboshi (諸星 大 Moroboshi Dai) is the widely known ace player of Aiwa Gakuen High School who is known as the Star of Aichi across Japan. Moroboshi is first seen being stretchered off early on in the last game of the Aichi prefecture tournament between Aiwa High School and first time winners Meihou High School due to physically clashing with Super Rookie Hiroshi Morishige. On the way to being treated, whilst on the stretcher he sees Shinichi Maki, Hanamichi Sakuragi and Nobunaga Kiyota who traveled from Kanagawa to Aichi to watch the game.

While he was gone, his team missed him greatly and they were down by a large deficit. Moroboshi arrives back on later in the game and closes the point deficit greatly almost single-handedly, showing his great skill. However there wasn't enough time and Meihou ended up winning narrowly.


Moroboshi seems to be friends with Shinichi Maki as while he was being stretchered off early in the game against Meihou he responded to Maki's call for his name. 

He is also modest about his skills in basketball, even denying his coach’s claims about him being able to match up with Sawakita.


Moroboshi's abilities were never shown, but Shinichi Maki notes him as the "Aichi's Star" meaning he has great skills as he almost single-handedly decreased the deficit of Aiwa Gakuen High School against Meihou. But still, they lost because there wasn't enough time and his coach believes that he is the one capable of defeating Eiji Sawakita even though deep inside he doesn't think he can.
