Considering these two statements....Ryuu will gladly support Haruka in her endeavors. Ryuu is stoic/cynical. Not Sasuke broody. He can be talkative, but he's very professional towards allies. Though...once he develops more of a friendship his...upbringing will make itself known.

I guess he'll have to develop some taijutsu to run away really really fast

Haruka and Ryuu will develope a beautiful friendship based on harming Dai's testicles for saying things that should not be said -
"Ryuu, hold him! I'll kick his balls so hard they replace his eyes!" - Fact: I once said this to my little brother.

Once (if) Haruka finds out about Ryuu's past, she will hug the shit out of him. Like, with giant, teary eyes and squishing him like a teddy bear and swinging him back and forth (with his feet dragging on the round since she's so damn small) going "You poor, poor thing!" over and over again xD

Was looking through Haruka's CS again and this made my mind laugh at the possibilities:"Will of SteelHaruka's will of steel is something that is believed to be inherited by the Hagane blood that flows in her veins. She is stubborn like few and once she gets an idea into her head, she will not stop until her goal has been accomplished."For some reason I've now got in mind a Naruto-Sasuke kinda relationship where Haruka makes it her goal to be Ryuu's friend. lmao.

She would be like that, if she decided that befriending Ryuu was something that she wanted to do. She'd follow him to the End of the World if that's what it took. If she set her mind on it, of course. She might not find him interesting enough for that.
