I swear are there no other deities out there and not this bitch????

there are indeed, remember thoth/tot from the harvest festival arc who held the seed of beginning? iruma having formed a bond with him during the quest, while reciting "hatsukoi memory". they are also a deity who just might be able to turn the tide.
here's to hoping!!
iirc, there are more deities apart from those two. princess shura is mentioned as one of the higher deities and i don't think much info was given about thoth beyond that arc.
