Description
Yūka Sasaki maintains a cheerful and friendly facade, easily identified by her gold-blond ponytail and a distinctive necklace. She jokingly claims superhuman strength, like piercing a heart with a touch, but cites an animal allergy preventing demonstrations near creatures like cats. Her energetic and caring demeanor centers on her childhood friend, Shinji Kazama, portrayed as her boyfriend whom she looks after due to his reclusive nature and class avoidance.
This amiable mask hides a deeply obsessive, jealous, and manipulative core. Her true power is necromancy, controlling corpses using a personal item from the deceased. This ability functions solely at night or in pitch darkness; daylight or bright light nullifies it. She reanimates Shinji's corpse using a torn piece of paper from his school test, presenting him as alive and compliant to conceal his death.
Five years before the main events, Yūka's obsession turned violent upon discovering Shinji on a date at a movie theater. Consumed by jealousy, she deliberately set the building ablaze. Shinji perished trying to rescue others inside, but Yūka concealed his death, reanimating his body with her power. She fabricated a narrative of them as mutual romantic partners surviving the fire together.
At the island school, Yūka continues manipulating Shinji's corpse to interact with classmates and sustain the illusion of his life. Her actions escalate when Nana Hiiragi uncovers inconsistencies. After Nana attempts exposure, Yūka retaliates by reanimating multiple corpses, including former students buried on the island, to hunt Nana down. During a confrontation at an abandoned shack, Yūka's inability to enter lit areas grants Nana temporary escape.
Ultimately, Nana deduces the nature of Yūka's keepsake for controlling Shinji and lures her to a seaside cliff. There, Nana reveals Yūka's history as a stalker, exposes her responsibility for the theater fire, and discards the test paper. Emotionally shattered and enraged, Yūka is subdued by Nana using a poisoned needle, resulting in her death. Her necromancy ceases, leaving Shinji's corpse inert. Government assessments estimated her unchecked potential threat level exceeded 500,000 lives.
