I'm only adding THREE more characters from Highschool DxD in my story.
You have 4 choices. Pick the two you would like too see the most.
1. Akeno Himejima
2. Rossweisse
3. Asia Argento
4. Xenovia Quarta
Let me know in the comments.
P.S.
I was thinking of making another Kagari x Highschool DxD story. Completely different from The Mysterious Fallen Angel.
