Nagato shares food only with destroyers and Hoppo.
Or maybe it's payback for the hishimochi.
But given that Nagato here also has orange eyes, horns (via the headgear), and is crazy strong - along with being built like Seaport-hime - I can see why Hoppo thinks they're related.
HEEEEY Nagatos sharing food instead of stealing it.
THIS Nagato - As far as I remember - only stole food once and that was most likely only due to Kaga (THIS Kaga has a broader range of who she's jerkass to). Otherwise, the closesed she ever was to stealing any food was when she tested to see if Akagi had poisend any of the sweet-potatoes.
