Description
Mitsuki Kanzaki, a 15-year-old high school student, navigates life with her stepbrother Yuya following their parents’ overseas remarriage. Her childhood, scarred by abuse from her biological father, left her emotionally guarded and distrustful of men, fueling her icy demeanor toward Yuya. She avoids calling him "onii-chan" and keeps him at arm’s length, even as they share a home.
Her reality fractures when Hiyori Kotobuki, the spirit of a girl obsessed with Yuya, possesses her. Bound by a magical chastity belt linked to Yuya, Mitsuki faces a perilous dilemma: the belt’s "feeling gauge" fills through romantic or sexual interactions with him, allowing Hiyori to ascend. If the gauge empties, Mitsuki risks death. Reluctantly entangled in Hiyori’s schemes, she vacillates between defiance and uneasy cooperation.
Initially aloof, Mitsuki’s walls crack under Hiyori’s meddling and Yuya’s unwavering kindness. Blushing fury follows each possession, her discomfort with intimacy laid bare. Jealousy flares toward Yuya’s childhood friend Yukina, exposing insecurities about belonging. A school play stirs unease as Yuya’s fictional choices mirror her hidden fears; a pool mishup forces her to accept his aid, nudging her toward vulnerability.
A forgotten birthday becomes pivotal. Yuya’s belated celebration, spurred by Mitsuki’s mother, softens her resolve. By the story’s end, the hesitant "onii-chan" slips out, signaling fragile trust.
Black-haired with blunt bangs and purple eyes, Mitsuki’s reserved style mirrors her introversion. Beyond Yuya and Hiyori, she bonds with classmate Ayaka while navigating tense dynamics with Yukina. Hiyori’s possession occasionally triggers astral projection, drawing cryptic aid from Neko, a peer aware of the belt’s mechanics.
Supernatural coercion and internal growth intertwine as Mitsuki grapples with trauma. Though Hiyori drives their forced intimacy, Mitsuki reclaims agency—expelling the spirit in crises, confronting her muddled feelings for Yuya, and balancing survival with tentative connection. Her journey stitches together fractured trust, the weight of familial bonds, and the slow unraveling of self-protective solitude.
