OVA
Description
Born Reina Ryuugu in Hinamizawa, Rena relocated to Ibaraki with her family during childhood due to her mother's career. Her parents' divorce, caused by her mother's affair and subsequent pregnancy with another man's child, inflicted severe psychological trauma. Rena blamed herself for the family's dissolution, rejected her mother, and developed intense resentment toward her birth name. She adopted "Rena" to symbolically remove the "icky" elements from her identity, though she later acknowledged discarding positive aspects as well.
In Ibaraki, Rena's mental state deteriorated significantly. She hallucinated maggots crawling under her skin, interpreting this as Oyashiro-sama's punishment for abandoning Hinamizawa. This condition, later diagnosed as Hinamizawa Syndrome—a fictional illness combining schizophrenia and delusional parasitosis—drove her to self-harm through cutting. Her instability culminated in violently attacking three male classmates with a baseball bat, permanently blinding one, and shattering her school's windows. Console-exclusive content suggests this outburst followed an attempted sexual assault, explaining the lack of charges. After psychiatric hospitalization and a suicide attempt, she claimed Oyashiro-sama commanded her return to Hinamizawa for survival.
Returning to Hinamizawa in April stabilized Rena's mental health, though psychological vulnerabilities persisted. She joined the village's after-school games club, adopting distinct traits including "kyute mode"—an obsessive fixation on collecting adorable objects or people while exclaiming "Omochikaeri!" She frequented the local junkyard, maintaining a secret base inside an abandoned van to store collections and seek solitude during distress. Rena exhibited dichotomous traits: outwardly cheerful, nurturing, and using verbal tics like "kana, kana?", yet capable of extreme perceptiveness and calculated violence when threatened or deceived. She reacted with particular hostility to lies or challenges to her belief in Oyashiro-sama, often shifting suddenly into aggressive states marked by a vacant expression.
Her relationships centered on fierce loyalty to her father and games club members. She harbored romantic feelings for Keiichi Maebara, demonstrated through competitiveness and gift-giving, while aware of Mion Sonozaki's affections for him. Protective instincts toward her father drove her to murder Rina Mamiya and Teppei Houjou in Tsumihoroboshi-hen after they attempted to exploit him financially, followed by a school hostage crisis triggered by paranoia from Takano Miyo's research notes.
In Rei, set years after the main events, Rena appears as an adult following the curse's resolution. By 1988, she attends Gogura University alongside Keiichi and Mion. A subsequent storyline set in 2019 reveals she has a son named Kihiro. Within Rei's OVA episodes, Rena participates in comedic scenarios including a swimming pool outing where club members conspire to steal Keiichi's swim trunks, and a magical mishap involving enchanted beads ("magatama") that force romantic attachments. Accidentally swallowing a red bead entangled her in chaotic romantic pursuits dictated by the white bead's possessor. Her adult design features a purple business suit and retains her signature asymmetrical bob hairstyle, now longer.
