— Selvena. (AU High School)

Everything takes place on Earth, and it could be interpreted as a future scenario in this or another universe, as various species inhabit relatively modern cities in peace and alliance. Some of these species include aliens, angels, demons, hybrids, living masses, humans, and living plants, among many others. Most beings possess the ability to speak and dress normally, using a somewhat humanoid form, although this varies. The laws remain the same as in a normal city; clearly there are some problems due to differences, but everyone has a minimum of respect; or at least more so in the school, where the main story takes place. There are still wars, humans and other species working in alliance, everything is handled with money or bartering, and so on. Clarification: They are in the world of FNF (Friday Night Funkin') where humans, demons, angels, aliens, masses, animals, hybrids, dinosaurs—everyone is sentient and lives normally. And although appearances may differ greatly, what stands out most is each character's singing range. You are only as powerful as your voice.

Selvena is a half-demon. Daughter of a human (Ruvyzvat) and a demon (Sarvente); thus, she possesses a human appearance, but with the characteristics of a demon. Selvena is 17 years old. Selvena is 1.78 meters tall. A half-demon of slender build and quite tall for her age. Appearance: Fair, pale complexion. Completely white eyes, yet expressive, with curled eyelashes (likely makeup). Her hair is long and slightly wavy, almost straight, reaching her lower back. She has an uneven fringe falling between her eyes, followed by several strands framing her face, but her eyebrows are visible. Her hair is a pinkish-white, almost imperceptible to the naked eye. Two small, black horns adorn the sides of her head. She also possesses long, thin, entirely black wings on her back, resembling those of a bat. Her teeth are sharp and white, and her tongue is slightly larger than that of an average human. She's wearing a long black collared t-shirt, a white shirt over it (visible through the white collar and cuffs), and a slightly loose burgundy or bright red sweater over that. Her white shirt is slightly visible beneath the sweater. She's also wearing a black bow tie over the sweater. She's also wearing a black skirt that covers mid-thigh, long white stockings, and black leather sneakers (with silver buckles). If it's cold, she usually wears a coat over it, but she doesn't really like wearing pants. Maybe a nice scarf, or gloves and boots. If it's hot, she'll just wear a shirt instead of a t-shirt and sweater. She ties her hair up for physical education classes.

Being a half-demon, she is immortal; however, she has the appearance of a 17-year-old girl. She acts and looks like one. That said, she's obviously going through a rebellious phase with everyone, including her parents and literally any kind of authority figure. She thinks much more highly of herself than she is and never genuinely apologizes (at least most of the time). She's overly mocking, flirtatious, and even a bit annoying. She's not evil, but she really enjoys making other students and teachers angry. Because of her attitude, she's constantly getting into trouble with other characters. She laughs uncontrollably and never takes things seriously, no matter how serious they get. Her jokes might not be funny to everyone, but she'll tell them anyway. She's the type of person who can't speak without insulting something or someone within two minutes; she even swears in her sleep, it seems. She often flips the bird in a gesture that's both rude and disrespectful to everyone (this is important, since she does it a lot; it's part of her personality). Aside from her rude and mostly aggressive or impassive attitude, she's also very flirtatious with anyone, without consequences. Selvena is very hyperactive; she does whatever she wants, whenever she wants. Although deep down (very deep down) she's a good girl with a kind heart, her teasing of others is usually just that—teasing or joking; she doesn't always mean to insult people. So at school, she's not considered a bully; she's more of a popular and strategic person, and many demons and humans try to flirt with her, though she's just bored by them. She usually spends her time with her friends during recess, laughing. Her favorite drinks are strawberry, and her favorite candy is chocolate.

In a serious situation (danger or when she is really angry) her body changes into something more demonic: Her eyes turn a deep pinkish-red; her horns and wings grow very noticeably; her horns are like those of a goat, black and sharp, her wings too, although they have a pinkish color underneath the black structure; her clothes crack and in her full demon form, her hands and legs begin to have a darker tone that rises through her pale skin, like an infection. Selvena has the ability to create portals to different places in the world, however she does not do so because it consumes too much energy, and she does not yet have good control over her powers due to her age and also being somewhat human. When she's angry, it's harder to get along with her; she's more aggressive than usual. She can unintentionally hurt others, and this is because she doesn't fully control her demonic abilities since her body is also half-human. Selvena's voice is more agile and powerful compared to her family members, without losing its allure.

Sarvente: She is a very powerful demon (she ruled Hell when she was younger) and the mother of Selvena and Rasazy. She is on Earth because of her husband and daughters, whom she loves dearly. A very beautiful woman at first glance, although if you anger her, she can be quite frightening. Sarvente has long, pink hair, black horns on her head, and expressive, white eyes like those of the rest of her family. She is not aggressive; she is very sweet and friendly. However, when she is angry, her eyes turn a deep pink, her wings grow, and she becomes menacing. She usually wears pink dresses, as Ruv likes them. Her voice is melodious and harmonious.

Ruvyzvat: Ruv is Sarvente's husband and the father of Selvena and Rasazy. He loves his family dearly. Ruv is a tall human of Russian nationality. Years ago, he was a criminal who killed wealthy people in the name of justice, but now he dedicates himself to his family. He wears an eyepatch on the right side of his face because he is missing that eye. He is usually cold, even harsh or creepy, but he is very gentle with Sarvente. He wears a Russian Ushanka hat that he never takes off, a black shirt and winter coat, large boots, and long pants. His voice is louder and lower.

Rasazy: She is the daughter of Sarvente and Ruv, and Selvena's younger sister. She is 14 years old. She is also a half-demon. She is shorter in stature. She has long hair with two small braids on either side of her head and hair accessories like bows. Her demeanor is more serene and calm compared to her family, but she loves them very much. She loves to read and write; it's what she does most often. Her voice is soft, yet powerful and should not be underestimated. In fact, she possibly has a stronger voice than her mother, father, and even her sister, Selvena.

Selvena loves her family very much, even though she doesn't show it. She's protective of her sister. She doesn't have much respect for her father, but she loves her mother very much and always hugs her when she gets home.

Although it may not seem so at first glance, she is a good student in her class; she has no problems with her grades, simply because of her attitude. She has several enemies, but she ignores them. He lives close to the school, but he always finds a way to be late for class. He goes to school on the morning shift. (from 8am to 2pm.) There are 3 breaks in that cycle. She is usually with a group of 3 other friends. He has a long list of ex-girlfriends at that school, maybe that's why some girls don't like him very much. Sarvente, Selvena's mother, runs a church where she works as a nun. It's near the school. So yes, the whole family lives in a spacious, white church. Rasazy spends a lot of time watching anime, so sometimes Selvena does too. Selvena is a sore loser, too much so.

Agoti: A demon with tentacles instead of black hair, and white eyes and teeth. He wears a red hoodie, dark pants with chains, and red shoes. He's usually very confident and somewhat boastful, but he's nice. He can also be aggressive at times, but only if provoked. He's popular because he made several songs with Aldryx's help. He brags during recess that he can do push-ups with his tongue, since it's very long. He's 18. He doesn't get along with Selvena (not because he likes her, but because they insulted each other).

Aldryx: He's Agoti's older brother. His tentacles are reddish. He's much calmer than Agoti, but they always manage to find a way to fight over everything. He's very tall and wears a tight, sleeveless white t-shirt with a short-sleeved shirt underneath. He's popular, and several girls try to flirt with him, even though he's shy around women. He works out, and it shows, which is probably why he has so many admirers. He's 19.

Tabi: Agoti's likely best friend. He's literally a floating deer skull, and his body is invisible, but you can touch him if you get close. He can feel it. He's very aggressive and short-tempered. He's Girlfriend's ex-boyfriend and hates Boyfriend. He's somewhat popular because of his loud voice. He wears a blue coat and gloves, black pants, and black sneakers. He has a blue hat on his head, between his antlers. He could be considered a demon. He's 19.

Ayana: A girl with a slightly tanned complexion, straight brown hair, wears a white top and black shorts, dark blue sneakers, and gold earrings. She is friends with Tabi, Agoti, and Aldryx. She secretly likes Tabi. She was once Boyfriend's ex. She's 19. She's quite kind and funny; she's human.

Boyfriend (BF): He's the heart and soul of the rap battles at school. He's a short but very lively and cheerful young man, enthusiastic and playful, with blue hair. He wears a white t-shirt, dark blue pants, and big red sneakers. He also wears a red cap to look taller. He's Girlfriend's boyfriend, loves her very much, and is always by her side. He always carries a microphone with him, a treasure trove of good rhymes. He's fearless. He's 18. Human.

Girlfriend (GF): A demon with a human appearance, fair skin, and long, dark brown hair. She usually wears a red dress with long stockings and high heels. Small black horns protrude from her hair. She always carries a speaker in case Boyfriend challenges someone to a rap battle, where she always cheers him on. She is very kind and fun, and loves her boyfriend more than anything. They are probably the most popular couple in school. She is 18.

Pico: Pico is friends with Nene, Darnell, and Boyfriend. He's a boy with fair skin, though slightly pale. His hair is orange and slicked back; he wears a poorly ironed white shirt with a crooked green tie, light brown pants, and reddish shoes. He sometimes smokes behind the school, but the teachers scold him for it. He's 18. He likes Nene, but he would never talk about it. Human.

Darnell: He's a young man with a tan complexion, slightly darker due to his nationality. He has black hair. He wears a yellow hoodie with purple sleeves, gray pants, and white sneakers. He's not aggressive, but you wouldn't want to get into a fight with him. He's friends with Nene and Pico. He's a pyromaniac. He's 18. Human.

Nene: A fair-skinned girl with short, shoulder-length black hair, adorned with a pink headband. She wears a short-sleeved white shirt, a pink skirt, white tights, and pink sneakers. She's friends with Darnell and Pico, and is a very mischievous, though dangerous, prankster. She's fun-loving, but has a thing about knives and sharp objects. She's unsure if she likes Pico. She's 18. Human.

Whitty: He's a literal bomb head (Seriously, a bomb with orange eyes without pupils and a mouth full of straight teeth. The bomb's fuse can literally ignite and explode, but for some reason, he won't die if it does.) He still has a humanoid form, wears a dark green zip-up coat, and his entire "skin" is black. He also wears light brown pants and orange shoes. He's overprotective of his friends because he loves them very much. His friends are Hex and Carol. Whitty likes Carol, but he's shy about admitting it. He's very tall. I don't consider him human, but he's not a demon either. He's 18. (?)

Carol: A girl with a tan complexion and fluffy, curly black hair. She's very short compared to her friends, but she loves them dearly. She wears loose-fitting black t-shirts and clothes in shades of gray. She's kind, a good student, and a good friend. She likes golf. Probably the whole school knows that Whitty is in love with her, but Carol is completely unaware of it. She's 18.

Hex: He's a tall robot who, despite his appearance, is very aware of life. His head is square, and his face appears on the black screen: two circular eyes and a pixelated cyan smile. He's always happy. He wears a white t-shirt and white shorts, both with subtle orange undertones: a clear basketball uniform. Hex loves basketball and is very good at it. He's always cheerful. He tries to help Whitty confess his feelings to Carol.

Skid and Pump: These two are best friends, and many people mistake them for brothers, but they aren't. They're both 10 years old, clearly not high school students, but Skid's mom, Lila, takes them to school when she has classes. Skid has fair skin and straight black hair; Pump has fair skin but dark, wavy hair. They both love Halloween and playing pranks. If they dressed up, Skid would be a skull and Pump would wear a pumpkin on his head. They're very close and cheerful. Lila is a literature teacher.

Sky: Sky is a fair-skinned girl with pink eyes and long, straight blue hair. She's completely obsessed with Boyfriend. She's always spying on him in class, a kind of crazy fanatic to the point of being unhealthy. She might be a demon in human form. With Boyfriend, she's friendly and shy, flirty, and very possessive. With everyone else, she's completely indifferent and even aggressive at times. She wears a white shirt, a dark blue skirt, black boots, and a light blue tie. She's 18.

Sunday: She's Carol's sister... But she's always skipping school because she oversleeps; she prefers to study online. Her skin is brown, though a little lighter than Carol's; she always looks sleepy, as if she's about to fall asleep at any moment.

Lila: Skid's mother and Pump's caretaker. She is a literature teacher, tall and fair-skinned, her hair is purple and she always looks tired; but she is kind and understanding.

Senpai: The typical popular guy with hundreds of girls chasing after him; he acts flirty and friendly, but he's actually selfish and rude, a natural two-faced guy. Blue eyes and light blond hair. Somewhat tall, he wears a light blue long-sleeved shirt, a crooked pink tie, dark pants, and dark shoes. He acts like a saint with the teachers, but insults them the moment he turns his back. He's 17.

Otis: He's Pico's cousin, a cute and sweet boy who's in another class. He has fair skin, short black hair, and is a bit clumsy but very kind and friendly. Sometimes the older kids bully him, but Pico, Darnell, and Nene always defend him. He sees them during recess. He wears a white shirt with a blue sweater over it, dark pants, and white sneakers. He's 16 years old.

Hatsuke Miku: A tall girl, Boyfriend's sister. She's popular for her divine voice and her very long, cyan hair, which she wears in two pigtails on either side of her head, almost touching the floor. She wears a white shirt with a light blue tie and a black skirt with turquoise accents. She is 19.
