Tobenai Tsubasa

Akira Godai is a brilliant student who one day had his father, an unsuccessful painter, killed in a traffic accident, forcing him to work part-time as a door boy at a bar in Ginza to pay for his school fees.
One day, Akira found a wallet containing a large sum of money left in a jacket entrusted to him by a customer, which he took with him to the bathroom, took the money inside and threw the wallet out the window; that quickly backfires, as a passerby saw him throwing the wallet, leading to his arrest. Now, as Akira is sent to prison, he'll have to struggle to survive in this harsh environment.
