This will be published by MF Bunko J. The author is Kinugasa Shougo(衣笠彰梧) and the illustrator is Tomose Shunsaku(トモセシュンサク). It will be released on 25th of July 2012. So it hasn't been released yet. The reason I am interested in this LN is because the author and illustrator were the scenario writer and character designer for the eroge "Akatsuki no Goei" series. Until this day, Akatsuki-no-Goei had the funniest dialogues and comedy in all the eroge I have seen. So I'm expecting this would also be good.

Souichiro(MC)Story Synopsis
I, Souichiro, 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"!? The ecchi Love-comedy of Delinquent X Devil girl X Angel girl given by the super popular creator duo!
The boy who is treated as a delinquent and he has evil looking eyes.
Teeri
The girl Souichiro picks up. She has small breast. A devil.
Elise
The one who appears in Souichiro's door. Big breast. A angel.
Momoe
Souichiro's classmate. She looks like a graceful rich girl.....
I hope this would turn out to be a good LN. The drawings would be way better than most LN.
