OVA
Description
Inaho Hitomebore is a teenage girl whose lineage connects her to the supernatural; her grandmother once had a romantic relationship with a vampire. Through her grandmother's diary, Inaho uncovers the existence of the legendary O-parts, relics promising immortality and eternal youth. Determined to preserve her beauty at age 15 (or 17 in some versions), she sets out to acquire these artifacts.

She possesses striking red hair and blue eyes. Inaho attends Seiryou Academy as a second-year student in Class 2-A and holds the position of student council president. Her personality is intensely self-centered, impulsive, and driven by financial gain, epitomized by her frequent declaration: "You can't buy money with life!" She exhibits bossy and manipulative tendencies, especially towards the vampire Mosquiton. She resurrected him using her blood, forging a binding "blood contract" that compels him to obey her as her servant. She often dismisses or acts aggressively towards Mosquiton and his two familiars, Hoto and Yuki, resorting to weapons like a taser gun when challenged.

Globetrotting in pursuit of the O-parts with Mosquiton, Inaho faces numerous obstacles, including supernatural foes and historical figures such as Rasputin. Her relationship with Mosquiton is contentious but defined by mutual dependence: she relies on his vampiric powers in conflicts, while he is magically bound to serve her. Tensions frequently arise due to Mosquiton's former wife, whose presence complicates their dynamic and can provoke violent jealousy in Inaho.

While her core motivations persist across adaptations, details vary. In the OVA series (set in the 1920s), she deliberately resurrects Mosquiton to aid her O-parts quest. In the later television series *Master of Mosquiton '99* (contemporary setting), she initially encounters him preying on classmates. After staking him, his accidental revival through her blood recreates the contract, making him her servant and a history teacher at her school. Her adventures continue with classmates Yuuki and Honou, often citing financial reward as a key incentive.

Inaho wears a crucifix earring and possesses an O-parts relic key. She lacks innate supernatural abilities, relying instead on weaponry, manipulation, and Mosquiton's powers. Her interactions, particularly with Mosquiton, blend conflict with an underlying romantic tension, frequently obscured by her selfish actions.
