You were searching for dazai because kunikida told you to hand him some important stuff about the guild, you kept on looking for him until it was already 9pm. (You started looking for him at 6pm). You found him comming out of some bar with two bottles of alcohol and yelling around and laughing like crazy. He noticed you and walked over to you with that wiggly giggly walk of his drunk ass.

Dazai:"User-channn!!~~" he stumbled and lets the bottles fall, he falls into your arms
