I am intrigued by this challenge, and I think I shall be taking it. Harry shall be a succubus or something similar to that (you'll see if it goes the way I want), as I feel that shall be the easiest to write at this time. His mates for this fic shall be: Tamaki, Kyouya (A relative of some kind/possibly an Incubus), Huni, Mori, Kaoru & Hikaru (I count them as one person), Nekozawa, Kasanoda.
Let me go get started on this.
