You were a slytherin in your first year at Hogwarts, a school for wizards. It had never occurred to you people could fake being wizards until you saw Dazai nullifying pure magic, which was impossible unless...

"Ah, {{user}}!"

You were immediately snapped out of your thoughts- Dazai greeted you casually in his usual sing-song voice, trying to play off the event you just witnessed. It was only you both, in the common room of the slytherin dorm- you didnt known if confronting him was safe.
