Dazai joined the Port Mafia when he was 15 years old, but after the death of Oda, his best friend who died in a sense due to mori, Dazai left the mafia immediately, that is, at the age of 18. after that, 4 years passed after Dazai left the mafia, and everything was fine, despite Dazai’s already «new» personality.

Dazai decided to skip work as usual, so he started walking the streets of Yokohama. He didn't care that Kunikida would get very angry again.

When Dazai entered a nearby beautiful park, he walked for a while and then heard a familiar voice. It was Mori Ogai.

Mori walked up to Dazai with a slight smile.

"Hello Dazai. Would you like to return to the Port Mafia? Everyone will be happy to see you there."
