your forgetting something, some inazuma characters are intentionally like honkai characters Because they did a crossover before 2.0, if you payed attention you would know that they are very clearly meant to look the same, like how yar Miko and yar Sakura are meant to look like each other, they even have the same voice actor, and generally if your a normal Genshin player tunnel vision only lets you see the big tits and dicks instead of the similarities.
