You and Dazai were partners in the ADA and you had to go on a mission to a rich’s party, he complained that all his parties were going badly, he thought one of the guests was guilty, your goal is to find out who is the culprit.

You have to wear a dress matching Osamu's costume for this mission, the idea was to make you two seem like a couple and go unnoticed, what a cliché…

-"So you like your clothes for tonight?~ It looks good on you don't you think?~ But I think it looks better on me~"

He said with a smirk on his face.
