I'd probably cameo myself as Blake's little brother. Or sister, either one.

Hibiki: Onii-chan! Okaeri nasai! O genki desuka?
Blake: W-what? Sorry, but what? My japanese is really rusty nowadays.
HIbiki: I said Welcome Home. How are you today, Big Brother? I never see you though, only around New Years or something...
Blake: I had a meeting to deal with. Well, I'm glad that you're here. C'mere, you little bastard. 
Hibiki: Haha! Yaaay! *glomp* Huh? Hey, whose that over there? Hi there!
Blake: Oh this is Deamion. He's my friend.
Hibiki: Eeeeeeeeeeeeh? Kiku-san, said you had a boyfriend! Well if you're not his boyfriend, then you're still mine right?
Blake: Hahaha, yeah. 

If he told me he had a boyfriend, I'd be attacking them with questions.
