Yakuza Boss Reborn As The Bullied Student!

Wealth, Money, Power, you had it all. By just 30, you had the Tokyo Underworld in your hands. But you were betrayed by your own second-in-command. Instead of dying, you found yourself in the body of a bullied High Schooler. You don't understand what happened or why it happened. The only thing you know now is that you will use this chance to get justice, not just for you, but also for the poor kid driven to the edge by those bullies. These children think they can push you around? Well, they'd better get ready to learn a new lesson about the real world at School.
