Yeah if a main char would become the subject of this magic, there will be a lot of flashbacks and "i love you" speeches to undo the effects of the magic. Just like FTGM, I also doubt a main char would become a shikigami.

About the resurrection, Kyouka likely needs a living subject. Otherwise it would be a total rip-off of Edo Tensei from Naruto. Truth be told I doubt there is still a corpse of Simon around, since the tower got destroyed and his corpse likely got lost at sea, however it is still a manga so logic doesn't always apply.
