And what about studies?
This is really funny.
Baji repeated a school year because he had difficulty keeping up with his studies. His own story shows that he needed to study, but he said he couldn't remember the material from class. When his mother cried about it, he took the situation seriously.
Tokyo Revengers Wiki
And there's that wonderful episode where he asks Mikey what to do to become smarter. Mikey basically replies:
"He wears glasses. Glasses make you look smart."
Baji goes to buy glasses with Mikey and Draken... and completely forgets to buy the glasses because a fight breaks out with other delinquents. 😭
In other words: Baji trying to study = a minor logistical catastrophe.
