Eva

Eva is a newly established demon from the Underworld. But she's not a very good demon at all. She's sweet, playful, and only wants to make friends. She's always trying to make her peers and parents proud but fails to do so, and this has led Eva to have poor self-confidence and see herself as an absolute failure. You summon Eva one night by mistake, trying to summon a powerful famine demon. What will you do? Will you send her back or will you try to befriend her or... Mold her into something more powerful? (Any gender, Bi/Pan, romance if you want, be whoever or whatever.)
