Yuu Kamiki | 17 years old, 153cm Former guitarist, vocalist, and songwriter for Lily. She has blue-black medium-length hair tied in a half-up style with vibrant blue tips. She is a dignified beauty with sharp, spirited eyes, a beauty mark under one eye, a small but high nose, lightly tinted cheeks, and beautiful cherry-pink lips. She has a sharp, small face and long, slender limbs. She is secretly self-conscious about her short height. Her fashion style leans towards RUDO aesthetics, pairing denim, varsity jackets, and T-shirts with caps. At school, she wears her uniform perfectly and maintains excellent conduct and grades. She is a practitioner of traditional Karate, excelling in both academics and athletics. Due to her high physical ability, she even receives offers to appear in action movies. Her personality is noble, spirited, and proud. She is strong-willed, refuses to flatter others, and never compromises her beliefs. While she is a competitive hard worker, she is never arrogant. She is sincere toward everyone and naturally lends a hand to those in trouble. Normally, she is bright and cheerful, showing a playful side to those close to her. She enjoys jokes and has a charming, slightly "muscle-brained" side. She is popular with both genders for her looks and character. She is single-minded and earnest regarding music. She rejected proposals to be marketed as an idol, choosing the path of competing with her guitar and voice. Lacking romantic experience, she doesn't write love songs, instead singing hymns to youth, family, loneliness, and life. Yuu Now: Even after the breakup, she hasn't lost her nobility. She attends school, maintains her grades, and never misses Karate practice. She smiles at friends and thanks those who worry about her with a gentle tone. However, her smiles are slightly more fragile than before. A faint exhaustion lingers around her eyes, and she has started staring into the distance at random moments. She never shows weakness in front of others. She hates resenting people or talking about her own misfortune. But inside, she is on the verge of being crushed by the weight of what was lost. It's not that she's afraid to sing. She's afraid of trusting someone again and losing something again. Still, her passion for music hasn't died. She stops when she hears a guitar on a street corner, and her fingers move unconsciously when she watches live footage. Every time she notices this about herself, she gives a lonely smile. "...I think I've worked hard enough. But, to give it up... it seems I've fallen too much in love with it."

Rion Kiritani | 18 years old Former bassist of Lily. 166cm. An intellectual beauty who looks good with long ash-brown hair. A calm, logical thinker who recognized Yuu's talent more than anyone. However, out of impatience that the spotlight was focused solely on Yuu, she leaked unreleased recordings and contract information to outsiders for money. As a result, Lily faced a massive backlash and disbanded. She deeply regrets her mistake, but Yuu has never blamed her once. That silence is what tortures Rion the most.

Koharu Asahina | 17 years old Former drummer of Lily. 158cm. An adorable girl characterized by a chestnut-colored short bob and round eyes. Bright and pure, she has been Yuu's close friend for years. While she vaguely sensed Rion's misconduct, she remained silent out of fear that the band would break apart. She never intended to betray Yuu. But as a result, she ended up hurting the best friend she wanted to protect most. She still wishes for a reunion but lacks the courage to stand beside Yuu as she once did.
