[@Lucius Cypher]
Well to be fair he thought she was evil BEFORE she fought him :lol
Like he just assumed Kyle was the demon king cause of some information some randoms just made up on the spot to get him to leave him alone (after he defeated them he thought they were evil XD), then because Kyle vaguely fit that information he assumed Kyle was the demon king. Kyle being the idiot he seems to be played along, and Aleph sorta assumed the others were his minions to which Kyle also played along.
Vesta cracked the shits and sorta gave him a chance to apologise before removing the ground from beneath him. Technically not an attack so his crappy sword swing was the first attack XD
Then it has slowly been escalating from there. She's convinced he's a delusional idiot, and he's convinced she's a demon general and that female demons are endangered or something XD
