Description
Tamaki Kasuga is a 17-year-old girl who relocates to the rural village of Kifumura to live with her grandmother, Shizuki Ugaya. Upon arriving, she discovers she is the next Tamayori Princess, a hereditary mantle requiring her to protect the supernatural seal on the dangerous artifact Onikirimaru, a task only possible for her bloodline.

Initially unaware of her heritage or spiritual abilities, Tamaki adjusts to her destiny while facing hostile supernatural entities like the slime creatures that attack her soon after her arrival. Takuma Onizaki, one of her destined guardians, rescues her, drawing her into the supernatural world.

Tamaki possesses a cheerful and gentle personality, often prioritizing others' safety over her own, which leads her into dangerous situations requiring rescue by her guardians. Despite initial powerlessness, she shows emotional resilience, supporting others with encouragement and a brave demeanor. Her determination is captured in her belief: "No matter how challenging it is, it's not impossible if you don't give up."

Her abilities develop gradually. She begins with basic spiritual awareness, perceiving spirits like her fox companion O-chan. Awakening to her role, she gains the capacity to use sealed artifacts from her grandmother for temporary defense against adversaries like Logos. By the climax of the first season, she fully awakens her powers, enabling her to create protective barriers, strengthen her guardians, and perform self-defense. Her most critical ability is sealing the Onikirimaru, unique to her bloodline.

Relationships are central to her character. She shares a complex bond with her five guardians, especially Takuma Onizaki. Their relationship evolves from friction to deep romantic involvement, revealing a past-life connection as reincarnations of a Tamayori Princess and an Underworld God who were lovers. This forbidden love culminates in defying sacrificial traditions to stay together "forever" after overcoming deception by her grandmother. Her dynamics with other guardians deepen: Mahiro Atori shifts from viewing her as a burden to protecting her like family; Yuuichi Komura offers brotherly reassurance; Shinji Inukai benefits from her encouragement as he seeks his place.

Tamaki is approximately 160 cm tall with long brown hair and brown or amber eyes. She typically wears a Japanese-style school uniform with grey socks and black shoes.

Her surname "Kasuga" means "spring day" in Japanese. Her hobby is visiting shrines and temples. She and Takuma are the first recorded Tamayori Princess and demon to become lovers.
