Movie
Description
Izumi Nase is a pivotal secondary character in the narrative, serving as the previous head of the Nase clan, a family of Spirit World Warriors tasked with managing supernatural phenomena and youmu within their territory. As the eldest sibling in a household without parents, she took on the role of mentor to her younger brother and sister, Hiroomi and Mitsuki Nase, instructing them in the ways of their duty. She is a young woman of eighteen years, standing at 170 centimeters tall with a birthday of April 7th. Izumi carries herself with an elegance befitting her station, pairing this with a frank demeanor and a characteristically kind expression. Her appearance is marked by neck-length black hair typically worn down, purple eyes, and a small beauty mark below her mouth, and she is often seen in shorts and long-sleeved shirts accessorized with necklaces and a bracelet.
In her capacity as clan head, Izumi represented her family in dealings with the Spirit World Warriors Society, working to maintain her clan's power against the Society's influence. This required considerable political maneuvering, and she frequently bore burdens alone, excluding her siblings from her plans and struggles in an attempt to protect them. Driven by an intense sense of duty, her approach to leadership was often perceived as harsh, with a resolve that never hesitated to employ ruthless measures when the family's honor or the world's stability hung in the balance. Her deep care for her siblings, while real, manifested in ways that led fans to question whether she was truly a loving parental substitute or a horrible one, given the dangerous situations she placed them in. This complexity extends to her motivations regarding the powerful youmu known as Beyond the Boundary, with viewers debating whether her actions were ultimately altruistic or self-serving.
Izumi's role in the story is largely defined by her attempts to control the threat posed by the half-youmu Akihito Kanbara. To this end, she hired Mirai Kuriyama, the last of a clan with blood-manipulating abilities, to assassinate Akihito. When that plan failed, she persuaded Mirai to sacrifice herself to extract the youmu from him. In a pivotal act that defined her arc in the Future movie, Izumi took a dangerous youmu into her own body from the antagonist Miroku Fujima, believing this would grant her the power to protect everything she held dear. The youmu eventually overwhelmed her, leading to a loss of control and a public revelation of her condition as a human host, after which she vanished into self-imposed exile and left the leadership of the Nase household to Hiroomi.
Her key relationships are central to her development. Her dynamic with her younger brother Hiroomi is particularly fraught, as he is forced to hunt for her after her disappearance. She later reappears as a hooded figure in a black bodysuit, wielding her signature weapon, and fights Hiroomi and Akihito. It is only through Hiroomi's refusal to give up on her and his insistence that they should have been there for each other that she is able to overcome the youmu's influence. This confrontation marks the climax of her character development, as she is ultimately saved and shown to be recovering, with life returning to normal by the film's conclusion.
Regarding her notable abilities, Izumi stands out as an exceptionally skilled Spirit World Warrior, even among her elite clan. She is one of the few individuals capable of using Glaciate Barriers, a technique so powerful that she can encase or sink her target's consciousness into a dormant state, which she used to suppress Akihito's youmu side. Her primary weapon is a double-bladed, double-edged naginata that is capable of separating into a three-section staff linked by a chain. Along with her proficiency in spiritual barriers, she is a master of the naginata and is easily capable of dual-wielding in combat. Her overall power is described as overwhelming, with abilities that include manipulating space to create force cages or slow enemies, a power that was enhanced by the youmu she willingly hosted inside her body.
