So Souji, looking mildly baffled, at first looks around to see if something scary is standing behind him, then over at Saizou - demonstratively ignoring them both - and then finally down at himself.

Oh. Oh.

Excuse him as he covers his mouth and has an urgent gigglefit, shoulders shaking as he leans against an adjacent tree. "I'm very sorry if I scared you. I- oh dear, you should've seen your face." Sorry, Mutsu. He's an actual little shit. "I'm just out training, see? I know I'm not supposed to wear this when I'm not on duty, but it was just practical."
