In the ProgramEdit
Yuko runs through the island in a complete panic when she witnesses the fight between Shuya Nanahara and Tatsumichi Oki. From her viewpoint, it seems that Shuya killed Tatsumichi, and she flees from the scene in terror.
She is later found by Yukie Utsumi's group who bring her in and she tells them about what she saw while on the island.
Later on, the girls bring in Shuya and help him recover. When Yukie brought them the news that he would recover. Yuko decides to put some of her poison into Shuya's food. Her plan backfires, however, when Yuka Nakagawa tastes Shuya's meal and dies. The girls all become panicked and Satomi Noda loses it and kills all her friends,leaving Yuko the only survivor who tries to tell herself that it isn't her fault. She then hears Shuya upstairs trying to get out and figure out what happened.
Yuko opens the door to Shuya's room confesses to starting an incident and runs up the stairs. Once at the balcony, she simply jumps off the lighthouse while Shuya checks on the other girls. Shuya then climbs to the top of the lighthouse to find Yuko's body being splashed by the waves below.
- Yoko was the last person in her clique to die and the only one who's death cause was suicide.
