Description
Hiyori Kotobuki, a spirit trapped between realms after her untimely death, clings to the living world due to unresolved romantic feelings for Yuya Kanzaki. Her inability to ascend compels her to pursue emotional and physical intimacy with him by possessing Mitsuki Kanzaki, Yuya’s stepsister. This supernatural bond materializes a chastity belt on Mitsuki, its heart-shaped gauge filling through Yuya’s romantic or sexual interactions. Each increment allows Hiyori to build stairways toward heavenly gates, while stagnation jeopardizes their existence.
Cheerful and bold, Hiyori’s assertiveness clashes with Mitsuki’s introverted demeanor. She hijacks Mitsuki’s body to orchestrate provocative encounters with Yuya, from spontaneous kisses to implied sexual acts, ignoring societal conventions and Mitsuki’s protests. These actions, fueled by fragmented memories that erase all recollections except her affection for Yuya, reflect her desperation to complete her mission.
Hiyori’s jealousy surfaces around Yukina Kiritani, Yuya’s childhood friend, whom she mocks as “that top-heavy woman.” Viewing Yukina’s physique and closeness to Yuya as rivalry, she manipulates Mitsuki to sabotage their bond. Though manipulative, Hiyori occasionally reveals vulnerability tied to her limbo, suggesting inner turmoil beneath her aggressive exterior.
Her interference inadvertently spurs Mitsuki’s emotional evolution, as the latter begins confronting her suppressed feelings for Yuya. Their shared emotions increasingly intertwine, muddying the boundaries between Hiyori’s obsession and Mitsuki’s hidden yearnings. The narrative culminates when an unintended heartfelt exchange between Yuya and Mitsuki completes the gauge, enabling Hiyori’s ascension. Her origins and the metaphysical rules binding her remain ambiguous.
Expanded media, including an OVA and live-action film, maintain Hiyori’s core role, emphasizing comedic and erotic obstacles in her mission. The live-action iteration preserves the chastity belt’s plot significance and her possessive manipulation of Mitsuki, amplifying visual sensuality. No adaptations expand her backstory or clarify her pre-death connection to Yuya, leaving these elements purposefully unexplored.
