Four and Six are my favorites, I think. (Yeah, I split it about there too.)

I really like Cecil, I just want to hit his pretty little blond head sometimes. He's like a really absent-minded kitten or something - absolutely adorable and sweet but I swear if Rosa and Kain didn't keep an eye on him he'd drown himself in the bathtub on accident.

Oh yeah, my ot3 for this game is Kain/Rosa/Cecil. I've established a lot of fanon in my head for those three...which was promptly smashed by After Years. Ah well.
