Hé's new and I'm still figuring him out, he's a very happy and very curious little guy who's sort of with the Unbound atm. He'll pelt anyone he meets with one million questions and general attempts at cheerfulness. Could be interesting with either of your characters.
Virga's an Aurora Basin tribrid who only recently started talking, he's very very introverted but also very curious, not the best at communicating. Might be up for meeting Zyanya, since she's a herdmate? Could also get yelled at by Ryouta, since he needs to experience more stuff in general.
