Aha, now there's some weirdness. Leo wonders if those are from coming here, or if Jack is some kind of yokai. Though probably a different one than he has back at home, since Leo caught that staring. Yokai from Leo's Earth wouldn't have batted an eye at him.

Leo has shaken very few hands in his life so instead of doing that he gives it a slap. A high-three, or low-three, in this case.

"Yeeeaaah, the shell doesn't make it easy." He lifts up one foot, revealing it is bare and nothing at all like a human's. "And shoes are pretty rough to find, too. Back home everything I have is a few sizes too big."

Leo actually does enjoy wearing clothes as a form of self expression, it's just getting things that fit that's a problem. It's why his usual go-to is a hoodie.
