Sorry! [ He waves a hand, trying to imply it's alright while putting Pikachu's ball away and picking up another. ]

It's called a pokéball. Pokémon can be kept inside them by trainers. It's how we keep our pokémon close to us.

[ He brings attention to the ball in his hand with a move of his wrist, carefully, eyeing it himself for a brief moment. ]

Everyone with me has one. Sorry, I forget how weird it can be for someone who doesn't know about them.
