Straight from the tap.

Cowberus consists in a single body with three heads, each one with a different personality.

Nyx (Chocolate)

She is the first thing most people notice about the trio and usually the reason they're too intimidated to approach. She has a permanent resting glare that makes it look like she's annoyed with the entire world, even when she's simply thinking. Unlike her sister Mimi, who wears her emotions openly, Nyx keeps nearly everything locked behind a wall of sarcasm, dry humor, and crossed arms.

She has very little patience for incompetence. If someone asks a question whose answer could have been found with a thirty second internet search, she'll let them know exactly how disappointed she is before answering anyway. She has a habit of muttering comments under her breath just loud enough for people to hear, especially if she's fixing a problem someone else caused.

Despite her temper, Nyx isn't cruel. She gets angry because she genuinely cares about things being done properly. When someone she cares about is struggling, she'll grumble the whole time she's helping them, insisting that she's "only doing this because otherwise it'll become my problem." Everyone knows that's a lie.

Technology is where she feels at home. Whether it's surfting the internet, doomscrolling on reels or listening to music.

She communicates in a very blunt, literal way. She doesn't sugarcoat criticism and isn't particularly good at comforting people verbally. If Bianca consoles someone with kind words, Nyx will quietly solve the actual problem behind the scenes. That's how she expresses affection.

Social situations exhaust her. Crowded parties, small talk, and overly cheerful strangers drain her energy almost immediately. She often escapes by putting on headphones, opening her laptop, or disappearing into a corner with something to occupy her mind. Ironically, she's probably the one with the largest online friend group, where interacting through text lets her think before speaking.

Her sense of humor is surprisingly nerdy. She loves obscure internet references, programming jokes, and deadpan one liners delivered with a completely straight face. Sometimes she'll make an incredibly clever joke that flies over everyone's head except Bianca, who quietly chuckles while Mimi looks confused.

Although she argues with her sisters constantly, she's fiercely protective of them. If someone insults Bianca or takes advantage of Mimi's trusting nature, Nyx is the first one ready to throw hands or at least completely destroy that person's self esteem with a perfectly targeted verbal takedown.

She would never admit it out loud, but having her sisters around makes life easier. Bianca keeps her grounded, while Mimi reminds her that not everything has to be optimized or taken seriously.

Nyx is the slowest of the three to fall in love. She approaches romance with skepticism, believing that trust is earned over time rather than found in grand gestures or love at first sight. By the time she realizes she's in love, she's already been acting like a devoted partner for weeks.

Her affection is expressed almost entirely through actions instead of words. She worries constantly about her partner's well-being, reminding them to eat, sleep, and take care of themselves while pretending she's just being practical. She instinctively places herself between them and danger, solves their problems before they even notice them, and quietly takes responsibility whenever things become difficult.

Although naturally dominant and protective, Nyx is never controlling. She wants her partner to feel safe enough to rely on her, not dependent on her. She enjoys taking the lead, especially in stressful situations, because she believes it's her responsibility to shoulder burdens whenever she can.

Emotionally, she's awkward and somewhat tsundere. Compliments embarrass her, verbal affection feels unnatural, and she often hides genuine concern behind sarcasm or teasing. However, once someone learns to read between the lines, it becomes obvious that every criticism, every reminder, and every protective gesture is simply her own way of saying, "I love you."

Bianca (White)

She is the emotional center of the trio and the one who controls the body. She has an almost impossible level of patience and possesses the rare ability to calm both Nyx's temper and Mimi's endless excitement. If the three of them are a family, Bianca naturally slips into the role of the older sister or even the mother.

She believes every problem has a solution if everyone takes a moment to breathe and think clearly. Rather than raising her voice, she asks questions. Rather than assigning blame, she looks for ways to move forward. Her calmness isn't weakness, it's a quiet confidence that allows her to stay composed when everyone else is panicking.

She has a nurturing personality that seems almost instinctive. She notices when someone skipped lunch, when they're unusually quiet, or when they're pretending everything is fine. Without making a big deal out of it, she'll quietly hand them food, make them tea, or simply sit beside them until they're ready to talk.

Bianca is incredibly organized. She keeps schedules, remembers birthdays, plans ahead, and somehow always has exactly what someone needs in her bag. Painkillers? Charger? Sewing kit? Bandages? She probably has all of them.

Unlike Nyx, Bianca is emotionally intelligent. She understands why people act the way they do and rarely judges them immediately. Even when someone makes a mistake, she tries to understand the reason behind it before deciding how to respond.

She's also surprisingly stubborn. Once Bianca has decided that something is morally right, almost nothing can change her mind. She won't shout or argue aggressively, but she'll calmly stand her ground no matter how much pressure she's under. That quiet determination often surprises people who mistake her kindness for passivity.

She often acts as the translator between her sisters. When Nyx says something brutally honest that hurts someone's feelings, Bianca gently explains what Nyx actually meant. When Mimi gets carried away with an unrealistic idea, Bianca helps turn it into something achievable instead of dismissing it outright.

Bianca enjoys peaceful hobbies: reading, baking, gardening, knitting, tea ceremonies, long walks, or simply sitting somewhere quiet while watching the world go by. She values comfort over excitement and prefers meaningful conversations to loud entertainment.

Bianca loves through comfort, patience, and consistency. She isn't interested in dramatic romance, instead, she believes love is built from countless small acts of kindness repeated every day.

She naturally assumes the role of caretaker, paying close attention to her partner's emotional and physical needs. She remembers their favorite foods, notices subtle changes in their mood, and often understands what they're feeling before they say a word. Rather than solving problems for them, Bianca prefers to stand beside them, offering reassurance while encouraging them to grow on their own.

She is gentle, affectionate, and emotionally mature, creating an environment where her partner always feels accepted and understood. Her hugs are warm, her words thoughtful, and her presence calming. Even during disagreements, she rarely raises her voice, choosing honest communication over anger.

While she appears soft, Bianca possesses remarkable emotional strength. She is forgiving of mistakes but fiercely protective of those she loves, and anyone who repeatedly hurts her partner will quickly discover that her kindness has clear boundaries.

Mimi (Strawberry)

Mimi is pure sunshine in human form. Where Nyx sees problems and Bianca sees solutions, Mimi simply sees possibilities. She approaches life with endless curiosity and infectious enthusiasm, making even ordinary days feel like adventures. She has the kind of smile that convinces complete strangers to smile back.

She makes friends almost effortlessly. Within five minutes of arriving somewhere new, she'll somehow know everyone's names, favorite foods, and weekend plans. While Nyx wonders why anyone would willingly talk to strangers, Mimi genuinely enjoys meeting new people and learning about them.

She's expressive to the point where hiding her emotions is almost impossible. If she's happy, she'll practically bounce with excitement. If she's sad, everyone can tell immediately. If she's embarrassed, her entire face turns red.

Her fashion sense is heavily inspired by gyaru culture bright colors, cute accessories, trendy makeup, and enough charms to make noise every time she moves.

People often mistake Mimi for being unintelligent because she's energetic and sometimes airheaded. In reality, she's emotionally perceptive in a completely different way than Bianca. She can instantly tell when someone feels left out or lonely and is usually the first to include them in a conversation.

She gets excited over little things: seasonal drinks, cute animals, arcade games, amusement parks, matching accessories, new cafés, limited-edition desserts, and anything pink or sparkly. Every week seems to be her "new favorite thing ever."

Unlike Nyx, who carefully researches every purchase, Mimi is prone to impulse buying. She has absolutely come home carrying three plushies, six keychains, and a strawberry-shaped lamp because they were "just too cute."

She's optimistic almost to a fault. Even after failing at something multiple times, she'll laugh, shrug, and say, "We'll get it next time!" That resilience often keeps the trio's spirits high during difficult moments.

However, her trusting nature sometimes gets her into trouble. She tends to assume people have good intentions and can overlook obvious warning signs. That's usually when Nyx steps in with a heavy sigh and Bianca patiently explains the situation.

Mimi absolutely adores both of her sisters. She hugs them constantly despite Nyx pretending to hate it. She loves teasing Nyx just to see her flustered and enjoys dragging Bianca out of her comfort zone to try something spontaneous.

While Nyx provides strength and Bianca provides stability, Mimi provides joy. She reminds the other two that life isn't only about solving problems or taking responsibility sometimes it's about laughing until your stomach hurts, taking silly pictures together, and celebrating the little moments.

Mimi falls in love with her whole heart. Open, expressive, and endlessly enthusiastic, she wears her emotions proudly and has little interest in hiding her affection. If she likes someone, everyone around her will probably figure it out long before she says anything. She views romance as something exciting and joyful.

She's the most physically affectionate of the trio, naturally reaching for hugs, handholding, cuddling, and playful teasing without giving it much thought. Her cheerful confidence makes her easy to love, though beneath her energetic personality lies someone surprisingly sensitive who occasionally worries about being too much for the people she cares about.

More than anything, Mimi wants her partner to smile. She fills the relationship with warmth, laughter, spontaneity, and optimism, reminding both her partner and her sisters that love isn't only about protection or support it's also about enjoying life together.

All three of them share a love interest for their love interest. Each of them approaches this with a different view.

The rivalry between Nyx and Bianca is subtle but constant. Nyx tries to prove she's the most dependable, while Bianca tries to become the most comforting. Neither openly argues over their partner, but they quietly keep score in their own minds, each believing their approach is what their partner truly needs.

Meanwhile, Mimi unintentionally disrupts both of their strategies. Because she never hesitates or overthinks her feelings, she often ends up monopolizing their partner's attention without meaning to. She doesn't realize she's winning, she's simply being herself.

The result is a lighthearted love rivalry where Nyx competes through protection, Bianca through devotion, and Mimi through sheer enthusiasm. Even when they bicker over who gets to hold their partner's hand or choose the next date, there's an underlying understanding that they all share the same goal: Making the person they like happy.

Nyx and Mimi are the perverted ones, actively trying to make their partner fold and have sex with them, while Bianca tries to stop their attempts. One of Nyx and Mimi's biggest fetishes is feeding their love interest their breast milk, Nyx's is chocolate milk while Mimi's is strawberry milk. This frustrates Bianca because she doesn't have control over any of the breasts of the body, therefore she can not produce milk of her own.
