[The source of the summoning... well, yeah. Ryuji could never get the details right and if pressed by Achilles to dig deeper, he'd probably fumble through a shitty explanation of personas, how they manifest inside people, and how they're born out of the cognition of human's collective minds. And oh, yeah. There's a holy grail somehow involved with all of this too.

Weird shit. Totally unrelatable to a Heroic Spirit though.

Ryuji flashes an impish grin when the spell takes hold. He's used it enough times to know exactly what the sensation is that's flowing through Achilles' body right now. Like if he wanted to slam his hand on the ground, he could punch right through it. (He could already, which is terrifying enough, but this buff is particularly good for those beefy types who excel at contests of strength.)

Bonafide mage, eh? He's not sure he'd exactly call himself that. Almost everyone on his team was better at wielding magic than he was- the stuff that Ryuji concentrated on was almost always with an eye to making him physically stronger against shadows, or stun them into place.]

Yeah, man! Wasn't it cool? You should feel all revved up and shit. It's pretty damn awesome.

So like... you're familiar with magic, but you've never seen that before? [His SP's already taken a considerate hit from his casting this evening. Oh well, it felt good to have Achilles' attention on him like this. He felt valuable in some way.]

Uh... Yeah, I dunno. I can see 'em when I summon him, but I guess you can't. Might be 'cause you never went into the Metaverse.
