OVA
Description
Akina Nanamura serves as a shrine maiden and is Kazuto Tokino's childhood friend, residing near the Tokino bathhouse. Her spiritual abilities allow her to create barriers and wield demon wards. After the alien princess Hydra crash-landed on her family's shrine, Akina used these powers to seal Hydra's abilities as retribution for the damage, reducing Hydra to a childlike form while retaining an adult mind. This established a dynamic where Hydra works off her debt under Akina's supervision, though their relationship remains contentious, frequently escalating into physical altercations when Hydra mocks Akina's breast size – a recurring source of insecurity for her.
Akina harbors longstanding romantic feelings for Kazuto but consistently fails to act on them, leading to regret as his relationship with Princess Valkyrie deepens. She regularly visits the bathhouse, observing their growing bond without direct intervention. Her emotional conflict intensified when Valkyrie temporarily enlarged her breasts using the Key of Time in season two, fulfilling a momentary desire; this change reverted when Valkyrie reversed the Key's effects.
A unique fusion ability exists between Akina and Hydra: when their arguments escalate, they combine into the powerful warrior Akidra, merging their powers, personalities, and enabling internal communication. This fusion dissipates if they become too agreeable, linking their cooperation directly to conflict. Akina also exhibits an allergy to cats, revealed early on when Hydra comforted her during distress.
During season three, Akina confronted Valkyrie Ghost and participated in a treasure hunt ritual alongside Valkyrie and Kazuto. Her character development involves reluctantly accepting Kazuto and Valkyrie's impending marriage, though her unresolved feelings persist. In season four, following Valkyrie's physical split into separate child and adult forms due to a mural accident, Akina's interactions remain consistent with her established role, maintaining her shrine duties and complex partnership with Hydra.
