With Soren gone and Nedria and his siblings living in Ice Empire, Ryusei has no direct family left in Fire Empire. Well, through bloodline, at least. His closed off and general distrusting natural probably doesn't help him out much, either. I'd like to imagine he'd be pretty close with Andromeda, though. After all, the current Leader to Fire was a close friend of his father's. Until he learned to actually make friends with some of the other feline in FE, she'd probably be the only cat Ryu could trust enough.
