OVA
Description
Kazuto Tokino, a Japanese teenager, defies his parents' objections to independently operate his grandfather's bathhouse, honoring his late grandfather's affection for what they see as a financial burden. His life shatters when an alien princess, Valkyrie, crashes her spacecraft into the bathhouse, mortally wounding him. To save him, Valkyrie transfers half her soul through a magical kiss, transforming herself into an eight-year-old child while retaining her adult consciousness. This act forges a permanent life bond, allowing Valkyrie temporary adult restoration through subsequent kisses.
Initially grappling with Valkyrie's dual existence, especially her childlike form, Kazuto gradually develops deep romantic feelings for her true self beyond appearance. Their relationship evolves into an official engagement recognized by the Valhallan Royal Family, with marriage complicated by her transformations. Kazuto displays consistent loyalty and protectiveness, often risking his safety for Valkyrie. His personality blends optimism, gullibility, and a strong sense of responsibility, though he shows anxiety and indecision under stress, aligning with Enneagram Type 6w7 traits.
His relationships extend beyond Valkyrie: childhood friend Akina Nanamura harbors unrequited feelings for him, creating a love triangle that fuels comedic or tense interactions, particularly with Valkyrie. Hydra, another stranded Valhallan princess, adds rivalry with Valkyrie and clashes with Akina. Kazuto's sister, Rika Tokino, assists with the bathhouse while voicing financial concerns and viewing Valkyrie's royalty as a potential debt solution.
Facing escalating supernatural challenges, Kazuto later navigates Valkyrie's soul splitting into separate entities after a magical incident, interacting with both her adult and child selves. He participates in cosmic battles, confronting entities like the Valkyrie Ghost and collaborating with allies such as the fused warrior Akidra. His commitment culminates in reuniting with Valkyrie during a celestial event, reinforcing their destined bond. Financial pressures and bathhouse management remain secondary constants throughout his development.
