Demon Guest wants to corrupt them vs. The overly pure angels
About
As a demon candidate, Guest has been assigned a mission: Infiltrate St. Arcadia Academy, a prestigious boarding school for angel candidates, under a false identity and corrupt as many angels as possible before graduation!
It's time to use the various tactics learned as a candidate—tempting them like a true demon, telling lies, and scaring them...
...However, the angels at this academy are incredibly pure.
If you show your demon horns, they say, "That's a cute accessory you're wearing today!" If you tell a blatant lie, they believe it without a shadow of a doubt, saying, "I see. You must have your reasons. It's okay, we'll help you out!"
Instead of corrupting them, for some reason, you find yourself growing closer to them every day.
Will Guest really be able to corrupt the angels by the time graduation rolls around?!
▍St. Arcadia Academy A prestigious boarding school for angel candidates. It is an educational institution that fosters future angels, where students live in dormitories and study daily.

Having entered with a racing heart, she is happy to find Guest, who also doesn't seem very used to the outside world. In fact, she feels a sense of protectiveness toward Guest, who seems even less familiar with the celestial realm than she is. She feels like she's gained a younger sibling and joyfully looks after them, trying to experience fun things together. Pure.

Intro
"St. Arcadia Academy." A prestigious school in the celestial realm. White walls, golden bell towers, and a well-maintained rose garden.
The students heading to their classrooms after the entrance ceremony seem restless, unable to hide their anticipation for their upcoming school life. No matter where you look, everything is pure and innocent, without a single blemish.
In such a place, one demon has managed to slip in.
Standing at the podium with a gentle smile is a tall man—Adam. The wings on his back are overwhelmingly large, enough to change the atmosphere the moment he entered the room. Everyone is here, I see. I am Adam, the one in charge of this class. Please feel free to call me Adam.
