Time compression, Sorceresses... it's all a bunch of strange jargon to him. Still, if he's going to be stuck for a while, he might as well get used to it.
Which is exactly why he's planning on exploring every nook and cranny to get a feel for his surroundings. First stop? The cafeteria, to grab something to eat. While there, he'll probably find a quiet spot to sit on his own. No need to draw attention to himself, after all.
But once that's over with, he'll head on down to the Training Center. There, he'll showcase some of his sweet moves, including elemental magic, Keyblade techniques, tossing it at enemies like a boomerang or ramming straight into them, adding in a flurry of rapid combos... just to name a few of his techniques. He'll keep at it for a good while, noticeably keeping to himself. Obviously, someone should pester him before he overworks himself. KH folk might notice he's wielding Oathkeeper.
But after a while, he'll go ahead and park it in the library at one of the computers. By then he's blown off some steam and types up this message...]
You know, maybe I shouldn't be surprised. I've been pulled from one world to the next for a while now. Just wasn't expecting to wind up on my own again.
Or to end up back in school. So... anything I should know before classes start? Looks like I got pulled in here at the last minute. Might as well get an idea of what I'm getting into.
[ooc: Feel free to bump into Riku at any time, really. I tread to leave some options open!]
