As a veteran of Group C, I want to destroy mygo!

[My favorite child + mygo world view]
Yu Kamiya, who traveled to MYGO, witnessed the demise of C Group with his own hands. Even so, he believed that no one would betray Crychic until he saw his former companions abandon him and happily establish MYGO together.
In order to fight against the inherently evil pink-haired imp, Kamiya Yu decided to form a new band by himself, destroy MYGO with his own hands, and take back all his friends from the yellow-haired Aine!
The guitarist, the bassist, and then the keyboardist Akane Kurokawa, a brand new band, assemble, tool man, as long as we win against Bang we can win back our partners!
Everyone must come back, no one can be left behind, including you...
Toyokawa Shoko!
——But why are the tools also becoming a little weird? !
