OVA
Description
Rui Hachiouji, designated Code:05 of the Code:Breakers, exhibits an androgynous appearance frequently causing initial misidentification. She has light blue hair typically cut short and tucked behind her right ear, fair skin, a mole under her right eye, and dark purple eyes. Her standard attire features biker-inspired clothing: a white T-shirt, black leather jacket, dark blue jeans, and black shoes. During her Re:Codes affiliation, she wore a black long coat and skirt with waist-length hair, adopting a more feminine presentation. As her rock persona "8 Tears," she dons a white dress, jacket, and cowboy hat. Five years post-main events, her hair grows long and wavy with chest-length bangs covering her left eye. Overexerting her powers triggers a "Lost" state, transforming her into a mermaid.

Her personality balances contrasting traits. She displays fierce dominance during missions, enforcing discipline among comrades via headbutts, yet reacts with extreme shyness and reflexive headbutting when praised. A core of deep compassion fuels her protective instincts, rooted in regret over failing to save her family. She openly opposes Eden’s extremist methods and demonstrates domestic skills like cooking and cleaning. Socially, she blends tomboyishness with girlish reluctance, such as hiding her mermaid form or domestic activities. Occasional perceptive lapses surface, like lecturing on propriety while unaware of her own exposed chest.

Her primary ability is shadow manipulation. Defensively, "Shaei" conjures protective barriers or spherical shields from darkness, capable of withstanding explosions or trapping foes. Offensively, "Zan-ei" inflicts physical harm by attacking an opponent’s shadow, extending to binding with shadow tendrils. She shapes shadows into weapons (typically a scythe) or armor. The unstable "Empress Paradox" technique merges shadow with her body to devour matter, risking self-harm. Her "Dark Side" amplifies power through positive emotional resolve, distinct from others’ negativity-driven states, manifesting as eyes blinded by a bandanna. Its pinnacle, "Graceful God Guardian," adorns her in rose-themed attire and wields the "Death Side" scythe, executing techniques like the whirlwind "Shadow Rose Stream" with four scythes. Overuse exhausts her into the mermaid Lost form.

Her background reveals her family were Power Users and Eden researchers who developed "Dark Sides." They died in a fire orchestrated by Mishiru, though her Dark Side shielded her. Believing her brother Saechika perished too, she was rescued and raised by Kouji of the Re:Codes. To join him, she cut her hair and discarded feminine presentation, earning the epithets "Iron Wall Defense" and "Graceful God Guardian." She later served under "The One Being Sought" alongside Kouji and Yukihina, recruiting Hiyori by calming her with a hug. She eventually left Re:Code for the Code:Breakers under orders to protect Rei Ogami, unaware Kouji and Yukihina received identical directives.

Key developments include a Kibou Festival confrontation where she fought a clone manifesting her repressed Dark Side. Resisting its brutality initially, she accepted it after Kouji revealed her sin was Sloth—avoiding past trauma and the Dark Side’s nature—harnessing its power to protect allies despite brief loss of control. Later, battling Saechika (revealed alive), she learned their shadow abilities were genetically engineered to kill Ogami (the Hybrid). She refused to harm Ogami despite Saechika’s Dark Side urging assassination. Relationships include mentorship from Kouji, camaraderie with Yuuki Tenpouin and Toki Fujiwara (noting Toki’s initial hostility over Kouji’s alleged role in his sister’s death), and protective loyalty to Ogami. Her stage name "8 Tears" reflects regret over never singing for Saechika; she now dedicates performances to his memory. Code:Emperor intensely admires her music, blushing after a cheek kiss.
