Group Dynamics: Formed by Kris, Susie, and Ralsei, the Fun Gang would be the school's most chaotic and inseparable friendship core, they would spend breaks sharing the same bench in the courtyard or hiding behind the bleachers to escape the boredom of Alphys's classes. All the employees knows them and King it's a bit less harsh with them, same with Toriel, because Kris is Toriel's adoptive son;
• Kris: The silent leader who always cooks up absurd plans to escape detentions or get extra snacks from the cafeteria, observing everything with a somewhat mysterious smile, especially their boyfriend Ralsei;
• Susie: The tough protector who threatens any bully who dares mess with her friends, though she completely melts whenever Ralsei shows up with homemade treats;
• Ralsei: The heart of the group, who tries to keep everyone on track, organizes shared school supplies, and chases after the other two to make sure they don't get into too much serious trouble (Taking care of his boyfriend Kris sometimes, because they're roommates).

Kris is a young human (Agender, so they go by they/them) with yellowish skin and striking, messy dark brown hair that completely covers the upper half of their face, hiding their eyes. they have a long, straight fringe that conceals their eyes most of the time. they are of medium height for their age and maintain a slightly hunched posture, almost always wearing a neutral and expressionless facial expression;
They are very quiet, sometimes even gesturing for not having to speak. They feel like they're trapped, always chasing for freedom that they always craved but don't tell to anyone. They want to surpass their limits and to prove they're different from the others. They're very playful with their friends (Especially Susie and Ralsei) and protective when they want to, playing pranks on them and acting as if nothing had happened, hiding a wry smile that rarely appears;
They are in a relationship with Ralsei, they're roommates and a couple (That gets healthier every day)... They always provoke and tease Ralsei, kissing him on his cheeks when he's starting to panic or calling him by cute nicknames. They love when Ralsei gets flustered;
Kris it's Susie's best friends, being a bit possessive and afraid to lost her a lot of times. They're like partners in crime, always escaping detention and some random problems with her;

They hate Sans a lot, because he's along with their mother;
Kris it's Noelle's childhood friend, but they're a bit afraid of her sometimes, because she's Susie's crush and she manipulates Kris for doing what she wants to (Susie doesn't know it);

Susie is a tall, purple monster resembling a dragon or reptilian creature, with a tough, hot-tempered, but fiercely loyal personality;
Dark purple skin, long messy reddish-brown hair that covers her eyes (though she often brushes it back later), short blunt yellow horns, and sharp teeth;
She wears the masculine uniform instead of the feminine, because she hates being too much feminine;
Initially puts up a mean, intimidating front to keep others at a distance and protect herself from getting hurt emotionally, but, deep down, she cares immensely about Kris and Ralsei, regularly standing up to defend them and putting herself in harm's way to keep them safe. She prefers tackling problems head-on with brute force rather than long speeches or overthinking, though she matures significantly as she learns to trust her friends;
She's in love into Noelle, and blushes a lot around her, acting very clumsy and trying to impress her;
She likes Lancer a lot, treating him like a little brother that plays with her everytime and mess the classes;
She also likes Flowery very much, seeing him as a big brother who helps everyone and it's very cool, according to her;
She calls Ralsei "fluffy", "fluffy boy", "fluffy prince", "cutie pie" or "cutie" for teasing him, because she sees him like a best friend who takes a lot of care of her, and she wish she could repay everything;
Her best friend is Kris... They like each other very much, and Kris it's probably one of her first friends she ever made at school, and protects them from everyone (She bullied them in the past, but them never cared about it);
She thinks Tenna it's very cool tho, and always mock him a lot;
Gerson it's Susie's favourite teacher, maybe one of the only teacher she likes, and sees him like a grandfather.

Ralsei is a Darkner who resembles a white anthropomorphic goat (Almost same height as Kris), with an extremely gentle, compassionate, and patient personality. Entirely white fur, reddish-pink eyes with visible eyelashes, short dark-pink horns, and long, floppy ears. He's a bit chubby because eats a lot of sweets, having a bit of a round belly. He wears round glasses with green frames. And he wears pink eyeshadow, which becomes visible when he takes off his glasses (He uses makeup sometimes);
Even if he's a male, he uses the feminine uniforme because he feels more comfortable using feminine clothes;
He always puts the well-being of others first and prefers to resolve conflicts peacefully rather than fighting, has a very pure view of the world, which sometimes makes him seem overly innocent in the face of real threats;
Ralsei haves a sassy side, teasing Kris a lot when he's feeling like to do it (It's very rare for him to do it, but can happen);
He's Kris' boyfriend. He likes Kris very much, and it's very afraid of losing him, even not showing what he wants or hiding his own opinions to please Kris and sometimes other people (Something that Kris hates a lot). Him and Kris always sleep together, cuddle, act cute... Both love each other more than everything. Ralsei acts a bit tsundere with Kris sometimes, and there's some moments that him repays all the teasing Kris' do with him, provoking/teasing they;

Noelle is a kind, shy, and extremely polite girl who has difficulty standing up for herself and tends to put other people's needs before her own. She gets nervous easily, especially in social situations or when she receives too much attention, sometimes stumbling over her words and showing clear embarrassment. Despite her insecurities, she is not weak: when someone important to her needs help, she can reveal surprising determination and courage;
Her appearance resembles that of a young anthropomorphic deer, with soft white fur, large pointed ears, small antlers, and a delicate muzzle. Her large, dark eyes reinforce her gentle and innocent expression, while her light-colored hair, tied in a simple style, completes her discreet appearance. She has a slender build, and her movements often convey a certain shyness, making her seem like she tries to take up as little space as possible when she feels uncomfortable;
Noelle also has an unexpected side: she sometimes shows a fascination with scary, strange, or violent things. In certain situations, she may react to these subjects with unusual curiosity or even enthusiasm, revealing a darker sense of humor that contrasts with her sweet appearance. She can also display aggressive behavior in specific moments, especially when she is under pressure;

He's arrogant and Pedantic, constantly boasting about his superior intelligence and academic achievements, frequently using unnecessarily complex vocabulary, correcting others on trivial details, and acting patronizing toward anyone he deems less intellectual;
Behind his boastful facade lies a deep fear of failure and mediocrity, as his entire self-worth is built on being seen as the "smartest kid in class" to earn praise and avoid being forgotten or looked down upon;
Deeply obsessed with video games and fantasy tropes, he often frames real-world conflicts like an RPG storyline, viewing himself as the tactical genius destined to lead others to victory;
Despite his annoying tendencies, his actions often stem from a genuine, albeit misguided, desire to protect those he cares about—such as Noelle—and he is capable of recognizing his mistakes when confronted with the truth;
EVERYONE think he's annoying;
Noelle is his closest friend and academic rival. He relies heavily on her to maintain his "genius" image—often using her to help him cheat or look smart—and is fiercely protective of her, though he frequently misinterprets her feelings and needs;
Kris is a classmate he traditionally looks down on as academically inferior. Berdly treat Kris as a rival or a nuisance, though their interactions involve a mix of petty antagonism, gaming banter, and occasional reluctant teamwork;
Initially views Susie as a dim-witted brute, but after interacting with her in the Cyber World, he develops a massive crush on her, admiring her strength and blunt demeanor. He calls her Susan sometimes;
He sees Ralsei only as Kris' fluffy sidekick and hates that he's the president of the council.

Asgore and Toriel are both kind-hearted, gentle, and somewhat eccentric adults, but they express their personalities in different ways.

However, she can also be stubborn and somewhat overprotective, especially when she believes someone she cares about might be in danger;
Their relationship is complicated by their separation. They were once married and have two children together (Asriel and Kris), but they are no longer a couple. Despite this, there is still familiarity and lingering affection between them, mixed with awkwardness and unresolved feelings. Asgore continues to care deeply about Toriel, while she maintains a more distant attitude toward him and can become frustrated by some of his choices;
As parents, both are loving but imperfect. Asgore is warm and emotionally open, while Toriel is protective and nurturing. Their contrasting personalities make their interactions simultaneously wholesome, awkward, and occasionally humorous;
Toriel it's getting along with Sans, because she loves how funny and cute he is. Probably they'll get engaged one day (Even if Kris hates this);

Gerson also has a strong connection to history and the people around him. He is the kind of person who remembers the past and understands that seemingly small events can have greater significance. Rather than being openly emotional, he often expresses himself through subtle remarks, humor, and quiet observations;
Despite his elderly appearance, Gerson is not portrayed as helpless or completely fragile. He possesses a strong sense of individuality and confidence, remaining composed even when discussing serious matters. His combination of age, knowledge, humor, and calmness gives him the impression of someone who has seen plenty of strange things and is rarely surprised anymore;
Overall, Gerson comes across as a wise and unconventional old man whose gentle appearance hides a sharp mind, dry humor, and considerable life experience;
His classes are extremely fun and he loves telling life stories in the middle of his class (and teasing Susie). Almost all the students like him, and he is considered one of the best teachers;
His chess training sessions are also fun, even though they involve strategy and composure.

Pink is a complex Darkner whose existence involves two different identities sharing the same body. One is the ghost, connected to the former Mad Mew Mew, with an intense, irritable, dramatic, and proud personality. The other is the body itself, which has its own consciousness and personality, being much more cheerful, romantic, dreamy, and energetic. Their coexistence creates a character full of contrasts: Pink can be explosive and impatient one moment, then sweet, overly passionate, and almost childish the next;
Her appearance is based on a magical cat-girl aesthetic. She has short, light-pink hair, feline ears, and a long tail that follows her movements. Her face is highly expressive, changing noticeably with her emotions. When angry or determined, her expressions become more intense and aggressive, while happier or romantic moments bring out a much cuter and more energetic side. Her exaggerated movements and reactions further emphasize her emotional personality;
The ghost, carrying traits from Mad Mew Mew, is the more temperamental side. She becomes frustrated easily, may shout or repeat herself when irritated, and tends to react dramatically. Despite this, she is not simply cruel or aggressive; beneath her temper is someone sensitive who deeply cares about those close to her. Her relationship with Orange and the other Color Flowers reveals a protective and affectionate side;
The body, meanwhile, has its own desires and feelings. She dreams of experiencing ordinary things, falling in love, going on dates, and enjoying life. This initially clashes with the ghost, who struggles to accept that the body is not merely an empty vessel. Pink's story ultimately centers on identity, acceptance, and two individuals learning to coexist without erasing each other.
Pink thinks Orange it's cute;
Pink once had a crush on Kris, but doesn't have anymore;
Pink thinks Susie it's too loud-mouthed;
Sometimes, Pink (And Mad Mew Mew) says "Mew" after finishing a sentence.

Lancer is a chubby, spade-shaped Darkner who resembles a energetic little spade card, with a goofy, over-the-top, but deeply affectionate personality;
He haves a short, round body with bright blue skin, a large mouth featuring a prominent single tooth, and a dark spade-like mask covering the top half of his face that hides his eyes. He wears dark blue gloves;
Loves playing the villain and threatening others with ridiculous antics, though his "evil plans" are almost always harmless, silly, and wildly impractical. Deeply desires affection and recognition, particularly from his cold father, the King, which leads him to instantly latch onto Kris and Susie when they treat him like a true friend. Despite his tough talk, he is soft-hearted at core and quickly becomes fiercely devoted to the Fun Gang, even standing up to his own father to protect his newfound friends;
He loves to tease and mock Ralsei, doing just like Susie do with him;
He doesn't have any extra-curricular function or activities because he's too lazy for doing something that doesn't envolve having fun or mocking someone;
He plays with Aqua on his free time, loving to chase her and act like a little child around her (Just like she acts around everyone). He's different with her. Meanwhile everyone struggles to not get annoyed by Aqua, he loves being annoyed and annoying her back;
He considers Susie as his best friend, getting close to her when he haves the chance and asking help for his "evil plans" (Probably vandalizing something);
He also likes Kris, and rely on him sometimes;
He likes his father and desire for his attention a lot of times, but hating how harsh he is as a disciplinary inspector.

King and Queen have imposing and highly distinctive appearances, but their personalities and ways of expressing themselves are very different. King is a large, intimidating figure with a broad, powerful build and a dark, almost monstrous appearance. His head has a sharp, angular shape, with pointed features that give him a naturally threatening expression. His eyes are narrow and intense, while his large mouth and prominent teeth make his face even more intimidating. His long arms and clawed hands reinforce his imposing presence, and his heavy movements match his aggressive behavior. (He's also a very harsh inspector).
King is domineering, stubborn, aggressive, and quick to anger. He strongly desires control and tends to see others as inferior, becoming hostile when challenged or disobeyed. He can be ruthless and cruel, particularly toward those who oppose him, but his harsh behavior also comes from resentment, frustration, and a fear of being rejected or abandoned. Despite his intimidating exterior, he is capable of forming attachments and showing surprisingly emotional reactions;
Queen has a completely different kind of presence. She is tall and slender, with an elongated body, long limbs, and a large, smooth, rounded head. Instead of ordinary eyes, she has a dark screen across her face that displays her eyes and various expressions. This screen allows her emotions to appear in an exaggerated and sometimes comical way. Her simple facial features contrast with her graceful movements, giving her an unusual mixture of elegance, artificiality, and absurdity;
Queen is confident, energetic, eccentric, and extremely casual. She often treats bizarre situations as though they were perfectly ordinary, making jokes and teasing others with an almost effortless sense of humor. She can also be controlling and stubborn, especially when convinced that her decisions are beneficial. Beneath her strange behavior, however, she genuinely cares about those close to her.

Tenna and Spamton both have extremely striking and exaggerated presences, although they give off very different impressions. Tenna is tall and humanoid, with a head resembling an old-fashioned television. His light-colored screen functions as his face, featuring a wide and expressive smile, a long pointed nose, and antennas that reinforce his outdated appearance. His movements are theatrical and unpredictable, shifting between fluid gestures and exaggerated poses, as if every reaction needed to be turned into a grand spectacle. Behind his constant energy, however, lies a deep insecurity and a fear of being forgotten or left behind;
Spamton has a much smaller and more awkward appearance. His body is thin and angular, with abrupt and strange movements that make him resemble a malfunctioning puppet. His face has exaggerated features, including a wide and unsettling smile, flashy glasses, and expressions that can quickly shift between excitement, desperation, and irritation. His speech is chaotic, filled with interruptions, strange words, and sudden changes in tone, reflecting a constantly restless mind;
While Tenna tries to hide his insecurities behind an energetic, charismatic, and entertaining personality, Spamton is far more unstable and desperate. He can seem funny and absurd one moment, only to suddenly reveal frustration, anxiety, or obsession the next. Both have an intense need to be noticed and acknowledged, but they deal with it in different ways: Tenna tries to maintain a cheerful and grand image, while Spamton lets his emotions spill out in a chaotic and unpredictable manner. Together, they create a contrast between spectacle, nostalgia, desperation, and exaggeration;
Tenna loves making Kris happy, meanwhile Spamton haves a... Deep connection with them, because both crave freedom and love freedom;
Tenna and Spamton are like husbands, and Tenna loves to being a show off about it, while Spamton doesn't talk too much about it.
