[He just nods as Minato offers to give him a rundown. His brow furrows a little at the explanation--yeah, it sounds a bit familiar, in more ways than one. On one hand, he's pretty sure the guy in the mask said something similar, even if he can't for the life of him quite recall the exact words. More than that, though, his chakrams were of a similar concept. He was still fuzzy on the details of how losing his heart and becoming a Nobody had granted him the power to summon weaponry from Hammerspace, but he supposed those details weren't so important. The relevant part was that they were, in a way, an extension of his soul. Hell, one of the modification gears actually made the chakrams manifest in a manner that was supposed to be a direct representation of his personality (did this mean he was a ninja at 'heart'?), so this wasn't as shocking to him as it might have been to someone whose life hadn't taken such a turn.

So this Persona thing... is alive? [That part was new.] Like, okay, it's a part of my soul, I can handle that, but... it's actually like a sentient self-aware thing that has my back in a fight?

[He could get behind that.]
