@Asta, lets see,


 * 1) SlashDog (currently writing)
 * 2) Millicas sequel (wants to write for below too)
 * 3) High School DxD Zero (AKA Sirzechs' story)
 * 4) Story set in the ExE world (No DxD characters involved)
 * 5) A story on a certain exorcist (He probably wants to go ahead seeing how he intriduced the Extra Joker)
 * 6) And a story on the remaining two Longinus.

Total number at the moment is 6, it might go further along the line but i doubt the spin-off will be long. There will be less to write as things become more explored.

@Striker, that would be fun to watch. XD
