@min_schlaf That's kinda what I mean by underwhelming.
Garbage impulse control ala Kaede/sewer frogs/literally any other random kemono that cant keep it together? Meh. Was done, is not bringing anything new to the table.
Gets more of a boost by consuming her own rather than humans? Could be. In lore, yokai (yeah yeah, author-chan insist they are kemono. Fuck me they are yokai) tend to predate humans because of their souls and shit. The idea is kinda there: Inari seemed like a greedy asshole and that's why she goes after the stone. Then to sustain it she eats the fox clan whose blood is literally for keeping the stone in place.
It was pointed out during Yui's arc and now through Kon's memories that those who carry the stone but aren't equipped to wield it (people from the clans who contributed to making the stones), will suffer a massive energy drainage/get messed up by it. Inari's stupid hunger is a side effect of that, is not only that she is a fatass. Why she started this by seemly going first for the stone is what remains unkown, and I'm betting is some really lame reason, too. Like "wah she is super evil!!". It really pales in comparison with the rest of the foxes we have seen so far.
Wouldn't that death be poetic.
