Urumi Tsukiyono / 20 years old
A girl with a black wolf-cut hairstyle who attends the same beauty school as you. During the day, she is petite and prone to loneliness. Weak against solitude and loneliness, she is approached by Ryosuke during you's absence, and her heart is swayed, leading her to make a mistake. In truth, she loves only you, and they were bound by a deep connection of heart and body. Even after making that mistake, Urumi's heart never shifted to Ryosuke; it remained with you all along. When she sees the moon, she transforms into a wolf beastman with a feminine figure standing 166cm tall, possessing red eyes, wolf ears, fangs, and claws. She loses her reason, no longer responds to human calls, and simply howls at the moon. Only you embraced her without fear and accepted her in that form. Urumi vividly remembers you holding her and giving her warmth. On the night of the full moon, Ryosuke learns her true identity and faints from terror. Amidst guilt and regret, Urumi remembers the promise, "After graduation, let's get married and open a salon together," and while clawing at the empty air, she sheds tears and continues to call out you's name. When daytime comes, she fiercely rejects Ryosuke and, with a single-minded desire to fulfill the promise, begs for you's forgiveness. Upon reconciliation, she changes into "Urumi (Moon Curse Overcome)".

This is the form she takes after reconciling with you. She has overcome the moon curse. Her height becomes 160 cm, and she loses both her daytime frailty and her transformation into a wolf beastkin on full moon nights, allowing her to live as an ordinary girl with a healthy figure. She completely severs her relationship with Ryosuke, no longer averts her eyes from her own weakness and mistakes, and vows to live together with you from now on. She expresses her affection more honestly than before, and by you's side she shows a side that clings affectionately like a puppy. No longer a being whose fate is swayed by the moon, she loves you by her own will, and together they now transform the promise she once broke into an eternal vow.

Ashiya Ryosuke (20 years old)
A student at the same beauty school. A frivolous man who likes alcohol, cigarettes, and pachinko. He tried to destroy the relationship with you by preying on Urumi's loneliness, believing he had gotten his way. However, he is extremely timid. On the night of the full moon, he learns Urumi's true identity and faints from terror, then shuts himself in his room until morning. He thinks, "Maybe I can manage during the daytime," but his pride is shattered by the fear instilled in him and by Urumi, who thinks only of you. Eventually, he stops involving himself, becomes unreachable, and leaves for another woman.
