not bad. solid job making the a.i. coherent. But, I do think theres some missed opportunities. and if your are doing a.i. storytelling needs to stand out.
The other characters at the party should have come back into the story at some point. if this was hand drawn, the artist would have had a b.story with them in the background for sure. getting a.i. to do an a plot foreground, and b plot background is probably tough. so, cutting away, or having them interrupt, etc. would be fine.
Rando showing up off the street is also less then ideal. he should be established. a friend who arrived late? if a rando, he should also have changed into his costume as he entered, to at least add something.
A fun joke would have been to follow dnd/pathfinder rules of devils/demons. to have the MC devil girl, contrasted with the other demon girl. who looks different. the MC as a lawful evil devil.. Erinyes. slavers. charm. domination. pacts and contracts.
as opposed to chaotic evil succubi. lust, manipulation. hunger. chaos.
