Description
Mitsuki Nase, youngest scion of the prestigious Nase family of Spirit World Warriors, hunts supernatural threats called youmu. As a second-year high school student, she presides over the Literary Club. Her appearance features long black hair, red eyes, and a height of 165 cm. She is often seen enjoying sweets such as lollipops or popsicles, typically clad in a deep blue sailor-style school uniform.
Trained from childhood in self-reliance and detachment under her sister Izumi's influence, Mitsuki developed a reserved, guarded demeanor. Confined largely to the Nase estate, she missed typical social experiences and initially distanced herself from peers. Her duties included monitoring classmate Akihito Kanbara, a half-youmu, ensuring his dormant powers remained controlled. Despite this surveillance, she grew genuinely concerned for his well-being, particularly during his distressing youmu transformations. Their interactions frequently involved her teasing him, notably about his preference for girls wearing glasses.
Mitsuki combines a razor-tongued, near-sadistic exterior with deep loyalty and compassion. She advises others, especially Akihito, with calculated rationality. Initially wary of Mirai Kuriyama, another Spirit World Warrior targeting Akihito, Mitsuki's stance shifted to active support. She aided Mirai in capturing youmu for income, invited her into the Literary Club, and attended a lantern festival with her. Their bond deepened, culminating in a tearful reunion after Mirai's temporary disappearance.
Her Spirit World Warrior abilities include creating defensive and offensive "Glaciate Barriers," though she usually relies on her rodent-like youmu familiar, Yakiimo, for combat. Considered less skilled than her siblings, she sometimes requires their aid during missions. Mitsuki holds unconventional views favoring peaceful coexistence between some youmu and humans.
Key family dynamics shape her: frequent clashes with her brother Hiroomi over his sister-centric behavior contrast with their strong, protective bond. Together they monitored Akihito and undertook joint missions, like combating youmu during the Calm phenomenon. Her relationship with Izumi involved adherence to strict teachings about warrior duties, complicated by Izumi's eventual exposure as a warrior harboring an internal youmu. Following Izumi's departure after this revelation, Mitsuki and Hiroomi assumed leadership of the Nase clan.
In the spin-off "Idol Saiban!," Mitsuki appears in a chibi idol form alongside Mirai Kuriyama and Sakura Inami, participating in comedic courtroom trials overseen by Ai Shindou, diverging from her main series characterization.
Her story arc traces growth from isolation to forming deep bonds. She transitioned from enforcing family mandates to challenging them, opposing Izumi's suggestion to eliminate Akihito. The waning of her powers during the Beyond the Boundary events and subsequent Nase clan leadership marked pivotal points. After these events, she resumed daily life with Akihito, Hiroomi, and the reinstated Mirai.
