OVA
Description
Mirei Jinno was a second-year student at Houshou Private High School known for bullying specific classmates, especially Mutsumi Oribe and Mami Miura. She leveraged her sexuality for advantage, notably engaging in a sexual relationship with a teacher to avoid a test, an act witnessed by class representative Chitose Naruse, fueling their mutual hatred.
Physically attractive, she possessed thigh-length copper-red hair matching her red eyes and a notably generous bust. Her standard outfit featured a short white coat over a black half tank top, jean short shorts secured with a black belt, and black knee-high boots, plus a three-ruby necklace in the anime. Giant crabs later tore off her jacket, leaving her in the tank top and shorts thereafter.
Her personality displayed pronounced arrogance, selfishness, and a consistent bullying tendency. She relentlessly mocked Mutsumi's insect expertise, despite its vital survival importance. She initially refused to join the rescue mission for Chitose after a giant wasp abduction, prioritizing her own safety. She manipulatively used seduction, offering glimpses of her underwear to male classmates for food searches and later forming a strategic alliance through seduction with Atsushi Kamijo, plotting to eliminate Mutsumi and Ayumi Matsuoka. Her manipulation included groping a restrained Chitose under the false guise of checking for parasites.
After surviving a plane crash and washing ashore on "Little East Island," she joined survivors including Chitose, Atsushi, and Mami. Early on, she froze during a deadly butterfly attack killing classmates. She voted against rescuing the abducted Chitose, only reluctantly joining when Mutsumi emphasized Chitose's waterproof phone's utility. During the trek through tick territory, she mocked Ayumi's leadership but meticulously followed Mutsumi's survival instructions.
At a clinic, her antagonism escalated: she slapped Atsushi awake during a dobsonfly attack, tied up Chitose upon her awakening, and molested her while falsely claiming parasite checks. Giant crabs interrupted this assault, causing her to lose her jacket during a failed escape. Mutsumi's group later subdued and bound her and Atsushi. Chitose advocated abandoning them; Mami rejected Jinno's plea for help, altering their dynamic. Mutsumi argued to keep them only for maintaining group defensive formations during travel.
A pivotal shift occurred later. Freed during a merger with Marika Chuujou's survivor group, she participated in a scouting mission, clashing with Kasumi Momosaki. Her development culminated in a final act of redemption: sacrificing herself to ensure others' escape. As a giant centipede attacked a coast guard vessel, she used a fire axe to release the lifeboat carrying survivors. She faced the centipede without fear as the ship exploded, enabling the remaining survivors to flee the island. This self-sacrifice contrasted her earlier cowardice, completing her transformation.
The anime adaptation concluded her arc earlier, ending unconscious, bound, and facing abandonment by giant insects at the clinic, omitting her later manga redemption.
