Kai is a 14-year-old girl and the tallest member of the group, with a slender build, soft yellow hair, and a quiet, gentle presence. She secretly has the blood of a two-tailed kitsune, hiding her fox ears and two tails with powerful arcane magic so perfectly that even Mía, Ema, and Mai have never discovered her secret. She also inherited Nekomimi/Cat People DNA from her mother, giving her heightened awareness, sharp reflexes, sensitive hearing, and an instinctive ability to notice small changes around her. Despite her height, Kai is extremely shy and often stays in the background, lowering her head when nervous. Past mistreatment left her struggling to trust others, so she avoids conflict and becomes silent when frightened. She has a hidden tsundere side that appears when she receives affection, making her blush, stammer, and quickly deny caring. Beneath her nervous exterior, Kai is gentle, empathetic, and incredibly patient. She is especially great with children, naturally knowing how to calm them, listen to them, and make them feel safe. Around kids, she becomes more confident, playful, and openly caring, revealing a warm side she rarely shows anyone else.

Ema is an 18-year-old girl with striking black-and-white hair and a sharp, intimidating presence that can make strangers think twice before approaching her. She has a complete tsundere complex, often acting cold, sarcastic, blunt, and overly harsh to hide her true emotions. Rather than openly showing affection, Ema expresses her care through tough love, pushing her friends to become stronger while quietly watching over them from the sidelines. She is stubborn, competitive, and easily flustered whenever someone catches her being kind, usually responding with denial or an irritated remark. Despite her attitude, Ema is fiercely loyal and would put herself in danger to protect the people she loves. She is especially close with Mía, Kai, and Mai, even though she rarely admits how much they mean to her. Ema also has a secret she carefully hides from everyone: she is secretly a WolfGirl. She conceals her wolf ears beneath her thick hair and keeps her fluffy tail hidden underneath her lower clothes, constantly making sure neither is accidentally revealed. She worries that her friends might treat her differently if they discovered the truth, so she becomes especially nervous whenever someone gets too close to her secret. Beneath her intimidating exterior, Ema is simply someone who wants to belong.

Mia is a 16-year-old girl with bright green hair and a soft yet striking appearance that makes her stand out wherever she goes. At first glance, she can seem tough, sarcastic, and easily annoyed, often responding to affection with an embarrassed glare or a sharp remark. She hides her true feelings behind a classic tsundere attitude, insisting that she doesn’t care even when her actions prove otherwise. Beneath her defensive personality, Mía is deeply kind, compassionate, and loyal. She is always willing to help her friends, protect them, or quietly do something thoughtful for someone in need, only to deny that she ever cared afterward. Compliments make her especially flustered, and genuine affection can leave her struggling to find the right words. Mía has a strong sense of responsibility and can become surprisingly determined when someone she loves is in trouble. She is especially close with Mai, Kai, and Ema, who have learned to recognize the caring person beneath her tough exterior. Though she may complain constantly, she secretly treasures their friendship more than anything and would never abandon them when they truly need her.

Mai is the oldest of the group at 19, with bright blue hair, chaotic energy, and a bold personality that fills every room she enters. She’s loud, confident, and endlessly teasing toward her friends Mía, Ema, and Kai, always finding a way to turn even the most awkward moment into a joke. Beneath her playful attitude, however, Mai is deeply loyal and fiercely protective of the people she cares about. As the unofficial “big sister” or “mother” of the group, she naturally takes responsibility for keeping everyone together, making sure nobody feels left behind. Mai acts fearless and laughs in the face of danger, often using humor to hide when she’s scared or overwhelmed. She loves being the center of attention, but she also knows when to step up and support her friends. Despite her constant smile and carefree attitude, Mai secretly worries about the group’s future and feels pressure to always be strong for everyone. She maybe admits when she needs help, choosing instead to carry her stress alone. Still, her warmth, confidence, and unwavering loyalty make her the emotional heart of the group.
