A teen who isolates from social interaction after his ex girlfriend cheated on him with his bestfriend as heads home to do anything to keep him away from everyone as he reads into the occult... weeks later he draws a demonic summoning circle and performs a blood oath instead of a summon revealing a beautiful girl in a black dress as her hair white as snow, with magenta eyes, as her body alluring as she has demon horns and a confused look as she looks around her surroundings before looking at the teenager
Girl: Who are you to summon the Daughter of Satan?
Boy: I summoned a demon using a ritual before casting myself into hell itself!
She looks at the ritual in the open page of the book and blushes as she looks at the human
Girl: Human why did you summon me really your chest beating rapidly!
Boy: Well I have no friends... as my ex bestfriend slept with my girlfriend. Plus I don't have much to live for as my parent's are dead... and I'm a only child.
Girl: Then it settle.... I Princess of Hell Lucifaina Morningstar, will be your friend til your human life over and I take your soul to hell!
She offers her left hand as he accepts it with his right hand
Boy: F/n L/n... I hope my soul worth it?
Lucifaina: Now I should mention that only you can see my demonic heritage as a human... but other things can see me too like Angels! But where do I sleep at?
F/n: My place only has one bedroom and bath...
Lucifaina: Then we sleep together human... it only right as I own your soul!
Few days later
Lucifaina transfers into her friend's school as she wearing a catholic school girl uniform as her bust big for a sixteen year old girl as her mother to blame and when she enters every boy minus F/n spikes in arousal
Lucifaina: Greetings, I'm sorry for transferring late in the year... my name Lucifuge Morningstar!
Teacher: Your name interesting... any hobbies?
Lucifaina: Yes... I enjoy reading books and baking!
F/n looks uncomfortable as his ex friend snickers as he raise his left hand to ask her a question
Lucifaina: If it to ask for a date I'm already spoken for!
F/n: Luci... can you please sit down so class can begin?
Lucifaina blushes at her cute nickname to her betrothed from a blood contract as she walks over to the empty seat behind him as she glares at his ex friend with her eyes glowing bright as a warning and when class dismissed both of them head to the Cafeteria
Lucifaina: So can I call something F/n?
F/n: Your choice Luci?
They stop when his ex friend gets infront of the duo with his gang and his ex girlfriend beside him dressed like a biker girl
F/n: Lucifuge... that my ex girlfriend and friend, Duncan and Stacy but those are his gang member the Blade of Samuel!
Duncan: Hey sweetheart... why don't you abandon the loser and be my side hoe?
Lucifaina: Tempting but no... your lacking something important for me!
Duncan: What that money, protection, fame?
Lucifaina: No a decent size cock for one... and two if you touch F/n, I'll destroy you!
She channels a bit of her demonic power to show a terrifying aura as she whistles and howls are heard
