See Me / Shin Soukoku

When Dazai Osamu is out of town, and Kunikida has to do double the paperwork, Atsushi is often sent to more missions than ever. On one of them, he encounters a gifted multiple times stronger than himself. The gifted knocks him unconcious with a single blow. When he wakes up in his apartment a few hours later, something doesn't seem right. And he was right. Something was very wrong, and it didn't take him long to realise what (I'm not gonna spoil but the title kinda gives you a hint).
