Movie
Description
Shizuku Ninomiya serves as a Spirit World Warrior and teacher at Nagatsuki High School. She has light brown hair, often long or in a ponytail, brown eyes with golden hints, stands 168 centimeters tall, has blood type A, and a birthday on June 18.

Shizuku maintains a cheerful, lighthearted demeanor, frequently smiling even during youmu confrontations. Frustration surfaces when situations defy her expectations, especially romantic ones. Her persistent romantic rejections form a recurring pattern, often linked to qualities like flashy date dresses. This pattern influences her emotional state, leading her to channel frustration into youmu hunting. In social settings, a tendency towards alcohol consumption, particularly beer, emerges; she may demand refills and display irritation over service delays.

Trained in close-quarters combat, she unleashes swift and decisive physical strikes against youmu, demonstrating ruthlessness. Her abilities include creating protective glaciate barriers and manipulating earth through geokinesis, enabling tactics like fissure creation or defensive earth walls. She coordinates with fellow Spirit World Warriors, such as during shadow entity engagements in the Mirai-Hen storyline, though some targets evade defeat. Professionally, she notifies cleanup crews post-encounter and appraises youmu stones, including instructing others on valuation.

Her history includes growing up alongside Izumi Nase and Yayoi Kanbara, maintaining friendly ties. Despite combat proficiency, her personal life centers on her ongoing single status, humorously referenced yet prompting visible disappointment—like sitting alone at festivals after canceled dates. This aspect persists beyond the series, shown in the Mirai-Hen credits and Mini Theater OVA where she seeks consolation from Izumi following rejection. Her involvement extends to significant events like pursuing Miroku Fujima and witnessing Mirai Kuriyama's berserk state.

Her surname Ninomiya translates to "second temple/shrine," and her given name Shizuku means "droplet."
