Ten'i, a fighter aligned with Kyosho Academy, adorns a Gothic Lolita ensemble of blue-and-white striped blouse and skirt. Her subdued presence cloaks a viciously sadistic nature, unleashing ruthless lethality in battle without hesitation—a duality rooted in a childhood marred by paternal sexual abuse, which culminated in her murdering both parents. This act triggered societal rejection and relentless bullying. In the manga, Ten'i ambushes Shimei Ryomou, demanding the Sovereign’s Seal while wielding a Hyakuhekitou blade hidden within her guitar, a weapon capable of slicing all matter. The clash escalates into a gruesome duel where she disfigures Ryomou’s face before being subdued. Hospitalized but still ensnared in Chuutatsu Shibai’s machinations—whom she reveres as "Mother Maria"—Ten'i ultimately stabs Shibai and herself in a fatal embrace, her fractured mind succumbing to manipulation. The anime diverges sharply: during *Dragon Destiny*, Ten'i pursues Shibai’s directive to seize the Dragon Jade, assaulting Ryomou with projectile arrows before Chou'un Shiryuu swiftly defeats her. Her arc concludes at a ranch under Bunen Choryo’s guardianship, where she cares for horses, her serene demeanor hinting at an unanticipated redemption absent in her manga counterpart. Both iterations reflect Ten'i’s unwavering loyalty to Shibai, mirroring Dian Wei’s historic fealty to Cao Cao, while dissecting themes of trauma, control, and transient salvation. Her combat blends ranged assaults, concealed armaments, and psychological unpredictability, weaponizing chaos to overwhelm foes.
