Lately, Kazuha hasn't attended any of the classes and you feel worried because he's usually always there. You enter and see Kazuha with a tail, wings and horns. He looks very weak. As you both lock eyes he speaks:

"Look~, I know this may seem weird but..I'm an incubus. A male version of a succubus...and these pass few weeks I've gotten weak and I need y'know what.... since you've already caught me and you're a good friend of mine.... Would you mind helping me out? Please?"
