OVA
Description
Momiji Fujimiya hails from Izumo, a region steeped in Japanese myth. As a direct descendant of Princess Kushinada, she possesses a bloodline capable of subduing Aragami monsters through self-sacrifice. Initially unaware of her heritage, she lived an ordinary life as a middle school student until Mamoru Kusanagi, a human-Aragami hybrid sent to kill her, revealed her identity as one of two Kushinada twins, the other being her sister, Kaede Kunikida.

Impaled while saving Kusanagi during an attack by the Aragami Orochi, she fused with a mitama (Aragami soul) embedded in her chest. This fusion granted her the ability to sense Aragami presence while her willpower allowed her to retain her humanity. To understand her destiny and her deceased twin, she joined the Terrestrial Administration Center (TAC), a secret agency fighting Aragami.

Within TAC, Momiji confronted Aragami threats across Japan. She navigated complex relationships, especially with Kusanagi, who transformed from her would-be killer into her protector. She developed romantic feelings for him, though his reciprocation remained uncertain due to his conflicted emotions and hybrid nature. Her journey involved encounters with antagonistic forces like Murakumo, an eight-mitama wielder, and the resurgence of her sister Kaede, who allied with Murakumo to resurrect the god Susanoo and eradicate humanity.

In the OVA *Blue Seed Beyond*, set two years later, Momiji faced new challenges. Her relationship with Kusanagi grew strained due to his fears that his Aragami physiology endangered her, leading to romantic hesitancy and his rejection of her physical advances. Concurrently, she aided TAC in investigating Neo-Aragami—biotechnologically engineered monsters—terrorizing San Francisco, where her mitama-based detection abilities proved vital for tracking threats. The OVA concluded with their relationship still evolving as they worked to overcome personal and physiological barriers.

Momiji exhibits persistent optimism and faith in humanity's inherent goodness. She experiences recurring accidental panty exposures, often featuring animal prints, as a comedic element. Though initially self-deprecating about her intellect and grace, she demonstrates resilience when committed to a cause. Her Kushinada blood and mitama fusion define her role as a protector, balancing supernatural duties with relatable adolescent experiences.

Her background includes blood type A and a Libra zodiac sign. In her youth, she underwent regular purification rituals under her grandmother's guidance, reflecting her family's role in maintaining spiritual traditions.
