Okina island is a paradise for criminal warfare. Drugs, violence and dictatorship are just a seasonal norm. Between the white collar demons and the blue collar devils, everyone can find their place, some even with their head still attached. Debt rules everything here but one debt is more important than others. Five super powered adolescents are trapped in this world of drugs, crime and money as they are forced to pay a debt to a Yakuza group the only way they know how, robbery. As they navigate between school life, heists and keeping their identities hidden they find that there is more story to their debt than they ever knew and someone is pulling their strings aiding in their doom.
