They're my friends. [ Not like he doesn't have more, but-- ] My two best friends, really. From back home.

And they're nice guys, but also-- ahh, how should I say it? They like making fun of me a lot, y'know? It's so rude! [ Look at this 28 year old sulking over being teased by his friends.. this is why Mary is not the kid here. ] They're good guys though, so you should make sure to meet 'em sometime. Heisuke'll probably wanna play with you if you need someone to play with.

[ Except Heisuke is not 15.. but... Shinpachi can pretend, okay. Spoilers: he's just as much of an ass to his friends as they are to him. ]
