In the Program
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. It was Yuka's job to take the food to Shuya and she reckons she should test it first, stating that she wanted to see whether it gets the 'Yuka Seal of Approval,' but the acid kills her. Later while Shuya laments the death of each of the girls from the lighthouse, he describes Yuka as not ever letting anyone be sad around her.
