I mean, Goku is around but he's not all at the same time- he's not home very often, but when he's in Union and NOT spending time with his family, he's kinda out and about.

He can teach you to eat and become a champion of being a pig, Ichigo. See, humans totally eat six times their weight in food, Goku promises XD

But if Ichigo is dressed like that, Goku is probably wanna know if he's a fighter or anything. Because you know, battle addict.
