18+ Koakuma Teeri to Kyuuseishu!?

I, Souichirou, picked up this little girl on a certain rainy day. Even though she has pink hair and unfamiliar cosplay looking clothes, she is just a normal girl. If there is one thing not normal, then that would be: the single black wing, which is growing out from her back. She who claims to be a devil, says that she has no place to return to, so I decided to keep her in my house. But that isn't the only problem. Then on the next day, a blonde bishoujo claiming to be an angel visits my house. And according to this girl, I have hidden possibility to either become a "Saviour" or a "Super Villain"!?
