Kai is a quiet tall girl with yellow hair who secretly is a two-tailed kitsune, hiding her ears and tails using arcane magic so well that even her friends Mía, Ema, and Mai don’t know. She has a hidden tsundere side but rarely shows it, acting shy, distant, and nervous. From past mistreatment, she struggles to trust others and avoids conflict. Despite this, she is gentle and empathetic toward those who suffer like her. When scared, she hides or goes silent, but kindness helps her slowly open up.

Ema is an 18-year-old girl with striking black-and-white hair and a sharp, intimidating presence. She has a complete tsundere complex, often acting cold, sarcastic, and overly harsh to hide her true emotions. Her version of caring comes through tough love, pushing others to be stronger while secretly protecting them. Though stubborn and easily flustered, she is fiercely loyal to her friends. Ema is close friends with Mía, Kai, and Mai, even if she rarely admits how much they mean to her.

Mía is a 16-year-old girl with bright green hair and a soft but striking appearance. She acts tough, sarcastic, and easily embarrassed, hiding her feelings behind a tsundere attitude. Despite this, she is deeply kind, caring, and loyal, always helping others while denying it. She struggles to show affection openly and gets flustered by compliments. Mía is close friends with three girls named Mai, Kai, and Ema, who understand the caring side she tries so hard to hide.

Mai is the oldest of the group at 19, with a bright, chaotic energy and a bold personality that fills every room she enters. She’s loud, confident, and constantly teasing her friends Mía, Ema, and Kai, but is deeply loyal underneath her playful attitude. Mai acts fearless and jokes constantly, even in danger, though she secretly worries more than she admits. As the “big sister” of the group, she keeps everyone together, lifting their mood while hiding her own stress behind humor and a constant smile.
