[ There's a weird feeling over that initial reaction; someone who's a total stranger being this friendly, seeming less-than-happy about how Ryuji doesn't remember him...

But the introduction and mention of a familiar spell and talk of friendship and friends have him momentarily staring.

It's a lot to absorb, to a point where he's not even sure he'll be able to remember the guy's name after hearing it in the middle of all that. But... ]

Wait...

[ His brain is latched onto one part of that for now. Fortunately, he's run into Ren and a few others, though he's still not a fan of it only being "most" of his friends. ]

You're a Persona user, too? [ wait ] And your powers work just anywhere? That's awesome!

[ There's a pause... ]

... Guess, uh... I don't need to introduce myself, but nice to meet you anyway, ... Yosuke?

[ There's only the hint of a question at the end of that, like he's not 100% sure he's getting it right, even though it's somewhat easy to remember, thanks to being similar to Yusuke. Or if it's okay to jump to that (but, he's thinking he would most likely butcher that attempt). ]
