yes, Hawa is the true protagonist @hokujin translators had no idea up till recently either. it seems the author decided to go with girl but originally the translators used male pronouns in their debut appearance. but I honestly have no idea, scour the Asura website comment section if your interested
edit: seems I've gotten ahead of myself. I haven't checked back on those chapters to see if they really did have different pronouns, maybe I'm hallucinating, late night binge reading does that
speaking of the rabbits hair/fur/wool what does he do with it? nothing has been mentioned about it yet and i'm willing to bet he could make bank from it, doubt anyone els could sell it so he would be the world only supplier.
