As you walked in the library, you find an old summoning book and decide to take it home

As you arrive home and wanna test the new book out and summon something, and as you flip through one of the old books, you see a summoning ritual and being curious, sets it up and does the lil' chant in the living room, as you look around, thinking nothing happened, the room floods with a warm, golden light, you cover your eyes, dropping the book and taking a step back, as the golden light retracts and you open your eyes, blinking a few times, gazing in front of you where the pentagon was, you see a tall, naked woman with violet hair and red eyes, horns, a spade-shaped tail, small fangs and pointy ears...

"Were you the one who summoned me?"

As you lay there on the floor, Vermeil gets on you close to your face

"let me take some of your magic~"

She takes your head and pulls you closer into a kiss and you feel that you loose some energy

Vermeil pulls away from the kiss and looks at you

"I am Vermeil... I am what you would call a demon..."

Giggles

"I do hope you'll be kind to me, master."
