OVA
Description
Misuzu Jinno, a second-year Houshou Private High School student, previously bullied Mutsumi Oribe and Mami Miura before the plane crash stranded her on the island. She exploited her physical allure to manipulate others, including a teacher to avoid an exam—witnessed by Chitose Naruse, cementing their enmity.
Her appearance includes thigh-length copper-red hair, matching red eyes, and a large bust. She initially wears a short white coat over a black half tank top, jean short shorts with a black belt, and black knee-high boots. The anime depicts a three-ruby necklace, while early manga chapters show one ruby. She loses her jacket permanently after a giant crab encounter.
Arrogant, selfish, and lascivious, Misuzu manipulates, intimidates, and sexually coerces classmates for survival. She forced Mami Miura to expose her underwear to boys, groped Chitose Naruse under the guise of "parasite checks," attempted rape while Chitose was restrained, and refused to rescue Chitose after a giant wasp abduction.
Post-crash, she allied with delinquent Atsushi Kamijo to sabotage Mutsumi Oribe's leadership. During the group's escape through tick-infested terrain, she followed Mutsumi's survival tactics: muffling heartbeats and deploying warmed pebbles as decoys. Later, on a beach, she seduced Atsushi to cement their partnership. At a clinic, she bound and molested Chitose, removing her panties before giant crabs interrupted.
After being restrained for these actions and facing abandonment, Mutsumi's pragmatic concern over group weaknesses spared her. She then joined scouting missions and clashed with survivors like Kasumi Momosaki. Her arc culminates in self-sacrifice: wielding a fire axe to release a lifeboat during a giant centipede attack on a coast guard ship, enabling others' escape while she confronts the creature amid an explosion—marking her departure from prior self-interest.
Media adaptations differ: the manga includes her full redemption arc and sacrifice, while the anime ends earlier, depicting her restrained at the clinic as Mami Miura proposes abandonment during advancing giant insects.
