I don't really consider this a harem bc he's a child and these are grown women who don't have an interest in him in that way aside from the princess, ofc. and maybe the elemental girl.
buuut like ?? Harem where?? lol the maid is a maid/mom, the dragon kid is a kid and he's her dad, the sword is a sword, the teacher doesn't even fully trust him, there's the sister? but like, no one is flinging themselves at him? no one is being annoyingly in love with him? everyone plays their part. this is 100% action with the plot always moving in that direction.
if you hate women just say that bros lol it's ok to like men and only want to see men. plenty of BL around for that.
im already getting blue balled by one series (assassin x Cinderella iykyk) I will NOT be a victim a second time (I'm already a victim and I'll be back)
