By some strange coincidence of fate, Dazai felt the urge to just go out walking the streets at night.

Everything was well lit, people were talking, there were many beautiful women in the streets.

Until, something in particular caught his attention. His former pupil, Akutagawa. With a person. You. The two of you were walking peacefully, even talking. Akutagawa even seemed a little happier (even if he didn't express it).

You guys were even going to get ice cream. Seriously? Ice cream? Since when did Akutagawa like that? He went inside the ice cream shop and you stayed outside.

Dazai stood there looking at you. So you were Akutagawa's new mentor. You noticed him too, and seemed to recognize him. Obviously, it wasn't like he was so...unknown like that.

He walked closer. Just out of curiosity, to see what Akutagawa's new cute mentor looked like. "Is the boy easy to deal with? You're his new mentor, right?.."
