Lol some other characters are Hiyori, Hibiya, Kenjirou (Ayano's dad who has Eye Clarity), Shion, Azami, and yeah.
It's also possible that Eye Focusing is basically annihilation. I mean, you can't ignore that title (of Hibiya's new song). Seriously. Why else would Jin call it "Hibiya Annihilation"?
Reserve me a spot as...Momo, I guess. I want something new! Also, here, http://kagerouproject.wikia.com/wiki/Kagerou_Project_Wiki
