OVA
Description
Haruka Takamori emerges as a prodigious warrior from the past, once aligned with the Jougenshuu faction in their ceaseless conflict against the Noroi Faction. Sold into slavery during her youth, she found liberation after her captor’s demise, rescued by ninjas of the Crescent Moons. Her unparalleled combat prowess propelled her to prematurely earn the rank of Blade, though she defied tradition by rejecting the final ritual’s demand to surrender her chastity to her master.

Adopting the surname Takamori—merging "Taka" from Ikusabe Takamaru, the boy she vows to shield, with "Mori," emblematic of her guardianship—she infiltrates Ten Treasure Academy posing as a student, masking her true age to remain two years senior to Takamaru. Her dual mission intertwines safeguarding his destiny as the Crescent Moons’ 23rd master with her relentless pursuit of the Noroi Faction into the modern era.

Haruka’s combat capabilities surge through SP, a supernatural energy forged via intimate contact with Takamaru, amplifying her strength, reflexes, and senses. This power wanes without replenishment, necessitating strategic replenishing. Her signature techniques, Hawk Eye—revealing enemy vulnerabilities—and Thunder Blade Break—a lightning-charged strike—underscore her tactical brilliance. Despite battlefield poise, she shifts from timidity to unyielding resolve, maintaining honor even amid risqué scenarios vital for power renewal.

A crossover incident in *Taimanin RPGX* thrusts her into an alternate dimension, captured by the collector Shara. Depleted of energy, she allies with Masou Shizuka and Kotaro, leveraging ingenuity to escape, showcasing adaptability and steadfast loyalty against unforeseen adversaries.

Her narrative weaves duty with vulnerability. While inherently compassionate, Haruka grapples with insecurities in romantic or intimate moments, fearing extremes during charged encounters—a stark contrast to her composed elegance in combat. Branching visual novel endings hint at possible corruption or redemption, yet the canonical *Choukou Sennin Haruka: Haruka VS Escalayer* cements her enduring heroism.

Legacy-wise, her unresolved Blade ritual echoes the clash between tradition and self-determination. Bonds with allies like Narika Shihoudou and Subaru reflect mutual trust, while clashes with foes such as Tetra Sealer Ittou Hagane exemplify her tenacity against dire threats, cementing her role as both guardian and indomitable warrior.
