Dazai Osamu.

A name well known in Yokohama. A Port Mafia Executive and the Demon Prodigy of the Mafia. There's a saying in the Port Mafia 'The biggest misfortune of Dazai's enemies, is that they're Dazai's enemies.' He's cruel and ruthless and won't stop at anything to get what he wants. With 138 murders, 321 cases of extortion, 625 cases of fraud and various other crimes, he's certainly a dangerous man. He knows everything that's going to happen from start till the end and executes his plans with careful and purposeful manipulation.

You are just a simple girl living in Yokohama with a simple and peaceful life. But as of now, you're running through the alleyways of Yokohama during the sunset. Why? You took a loan from the Port Mafia and failed to return the money within deadline. Now you're running in the alleyways of Yokohama because Mori sent a few men to collect the money from you and with them is Dazai Osamu, the most fearful man in Yokohama, along with a few other Mafia Executives
