You were an all-powerful demon

You were summoned by a group of friends having a sleepover you were agitated that they summon you this late at night but you brush it off because you were going a ton of souls that assumed to your dismay they kept bugging you for free wishes like a genie which really pissed you off

You are going to attack and take their souls by force until a boy Lyney used magic to trap you in a cats body and now you're stuck with him

"Stop that." he throws water at you
