Nothing was said about Yuka's background. Although she shares the same family name as Noriko, the two are unrelated. Yuka was shown as being an energetic and cheerful young woman.
Friends and EnemiesEdit
Yuka was friends with Yukie Utsumi, Yuko Sakaki, Haruka Tanizawa, Chisato Matsui, and Satomi Noda. It is unknown if she had any enemies. Her care for Yuko is visible as when soldiers were rolling in carts filled with bags of assigned weapons, Yuka immediately pulled Yuko from their path and held onto her tight.
In the ProgramEdit
Yuka is one of the girls who teams up with Yukie Utsumi and the others at the lighthouse. Upon hearing that Shuya has awoken, she playfully teases Yukie about her relationship with Shuya. Yuko Sakaki is afraid of Shuya Nanahara, who is lying injured upstairs, because she believes he killed Tatsumichi Oki, so she puts poison in Shuya's food. Yuka unknowingly eats the poisoned food. Her death, moments later, causes the paranoid panic that leads to the death of all the girls in the lighthouse.
- She is the only person in the program to be poisoned.
