OVA
Description
Kazuto Tokino oversees the Tokino family bathhouse, having relocated there against his parents' advice to uphold his late grandfather's legacy. They viewed the establishment as a financial burden, but Kazuto embraced it as both a duty and a link to his grandfather. He resides there with his younger sister Rika, later joined by extraterrestrial guests.
His personality blends kindness, gentleness, sincerity, and deep thoughtfulness with unwavering honesty, responsibility, and reliability. He demonstrates persistent dedication and hard work, often adopting an optimistic perspective despite financial struggles that worry Rika. While inherently considerate and protective—shielding Valkyrie or defending Akina from manipulation—his trusting nature can make him gullible.
Kazuto's life shifts dramatically when Princess Valkyrie's spaceship crashes into the bathhouse, nearly killing him. To save him, Valkyrie shares half her soul, transforming her into a child while leaving Kazuto unharmed and forging an irrevocable soul-bond between them. He becomes her caregiver, managing her daily needs and mischief. Over time, romantic feelings for Valkyrie's true self develop, transcending her childlike form. Their shared soul enables Valkyrie to temporarily regain her adult form through an emotionally aligned kiss. Despite challenges posed by her shifting appearances, Kazuto commits fully to their relationship, becoming her official fiancé with plans to marry.
During Season 3 wedding preparations, an accident involving a falling mural splits Valkyrie into separate child and adult entities. Kazuto subsequently cohabits with both versions at the bathhouse, navigating this complex dynamic while indefinitely postponing their wedding. This arrangement triggers chaotic Season 4 misunderstandings, including Valkyrie's classmates mistaking her child form for her daughter.
Kazuto shares a close childhood friendship with Akina Nanamura, who harbors unreciprocated romantic feelings for him; he remains unaware of her affection, his commitment solely with Valkyrie. He maintains supportive relationships with Valkyrie's associates, mediating conflicts involving her maid Sanada and rival princess Hydra. He also interacts with other Valhallan royalty like Princesses Laine and Chorus during their Earth visits.
His name reflects his essence: "Kazuto" merges "harmony/peace" (和, kazu) and "person" (人, to), while "Tokino" signifies "time/hour/occasion" (時, toki) and "field/wilderness" (野, no).
