OVA
Description
Hikaru Izumi holds the position of student council president at St. Maris Academy, a school dedicated to training students to combat demonic threats. She possesses long black hair extending past her hips, striking red eyes, and a pale complexion. Her standard school uniform, signifying her role as a demon hunter, features a black skirt with red accents and thigh-high stockings. Hikaru wields a katana as her primary weapon, demonstrating exceptional swordsmanship that allows her to perform specialized techniques like the Cross Fire Light sword beam attacks. Her personality blends a clumsy nature with strong honorable principles and a generally friendly disposition.

A tragic past fuels her motivation: demonic entities killed her parents years prior, forging a lasting vendetta specifically against the demon Barmus. She also maintains a protective relationship with her younger brother, Shou Izumi, who appears in the original H-game narrative but not in the anime adaptation. Hikaru shares close bonds with fellow student council members Seira Kamui and Yuki Ayatsuji, forming a protective trio responsible for safeguarding the school. Despite their collective efforts, they ultimately fail to prevent the demonic takeover in the anime narrative.

In both the anime OVA and H-game scenarios, Hikaru faces capture by Barmus, who possesses human form through the delinquent student Genji Kuronuma. Following her capture, she endures multiple forms of torture, including forced public nudity during a school assembly and electric shocks administered via tentacle-like restraints. The OVA depicts her subsequent rape by Barmus and his demonic cohorts, an extended assault occurring before her school peers that culminates in her psychological breakdown. This trauma manifests through broken expressions, tearful resignation, and ultimately a vacant, unresponsive state.

The narrative concludes with Hikaru lying motionless on the school auditorium stage, heavily implied to have been impregnated by her demonic assailant. Alternative outcomes in the H-game's darker endings similarly result in her becoming pregnant with demonic offspring, aligning with Barmus's objective of transforming her into a vessel for breeding new generations of demons.
