Actually, just thought up something. Good way to get the two groups together. The group at the mirror could write to Tsubasa and tell him that they'll be getting help, they search for the others, walk in on them, and voila, three more people who don't know why their classmate is dead and there's a vampire in a room. The mirror was able to fend itself off from Kaku's full on charge of fright. Glass - 1/Kaku - 0.
