Description
Kouta Oyamada, a high school student relocating from rural Japan to Kunpō High School, carries the weight of a fractured past. Orphaned early and raised by his grandfather, he internalizes the elder’s counsel to prioritize maturity over romance—a principle tested when Chizuru Minamoto, a bold kitsune, targets him with unabashed affection on his first day in the city. Her public, provocative overtures earn Kouta mocking epithets like "Great Erotic King," yet their bond transcends gossip: a fusion ritual unlocks their shared five-tailed fox form, fueled by the Eight Dragons’ mystical energy. This union sparks physical metamorphosis in Kouta, manifesting vulpine traits and supernatural abilities.

His life grows more tangled with Nozomu Ezomori, a wolf spirit vying for his heart. Though torn by her rivalry with Chizuru, Kouta navigates a polyamorous path, honoring his primary devotion to Chizuru while accepting Nozomu as a secondary partner. His compassion surfaces in defending Nozomu from hostile confrontations and bridging frosty relations with peers like Akane Asahina, whose initial judgment softens into solidarity.

Antagonists test his resolve. Saku Ezomori, Nozomu’s brother, imposes a lethal seal to sever Chizuru’s proximity—a threat Kouta overrides through deepened fusion, winning Saku’s begrudging acknowledgment. Later, Tamamo, Chizuru’s nine-tailed adoptive mother, subjects him to arcane trials, ultimately blessing their union. These ordeals steel his commitment to shield loved ones amid supernatural and emotional stakes.

By adulthood, Kouta weds Chizuru, fathering a biological daughter and adopting Ren and Ai Nanao, twin spirit hunters folded into their unconventional family. His journey traces a shy country boy’s evolution into a guardian balancing mortal fragility and yokai legacy, guided by his grandfather’s ethos of deliberate choice.

Three companions share his home: Pochi the dog, Mike the cat, and Yarkovsky the goldfish. His name—combining "cultivate" (耕) and "steadfast" (太)—mirrors a life nurturing resilience. Compact in stature, he bears brown hair and silver eyes, subtle markers of a duality bridging human vulnerability and burgeoning supernatural power.
