"It's apparently real here," Iruka said flatly. Chakra was magic, magic was chakra, and Raidou was shitting - farting? - *butterflies*. IF that wasn't magic, then the guy had a strange idea of normality whereever he came from. Probably from another crazy island where everyone shitted insects that played "blue danaube."
Iruka gestured to the guy anyway. He looked lost, which meant for that one instant, some kinship because Iruka still felt lost. Everyone else adjusted like ducks to oil, but he hadn't. Yet. Or maybe everyone else was just good at pretending. "At least come in where it's not so hot." Might as well, since raidou'd all but invited the man in, right? Something like that.
