eliza is attracted to both ris' nursing side and the side of her that wants to stab people

Ris appreciates that. So many people get scared off by the stabbing! She can’t imagine why!

Sooga finds Rean's loyalty and caring very admirable traits, and he's happy to have him as a friend

Zelos thinks Ris is cute looking! I don't think Jun has really thought about it with Rean one way or another so far

Crow in Kaisou sure has noticed how pretty Rean's eyes are and thinks he's attractive but hasn't thought much beyond that yet

Crow in general canon has absolutely noticed that Rean is hot and that his pretty face AND personality are enough to get all the girls wanting the D. And a few of the guys. He could have anyone he wants if he would just, you know, notice that everyone's swooning over him.

Not Crow of course, that's crazy. Well. Crow is swooning but as a CHOICE, he'd be the crazy option. Go date Alisa or one of the other girls. Or the guys, if that's what you want!
