Corse Party D2: Depths of Despair
Yuka appears as a dark spirit inside the girls' bathroom and chases Ayumi with a knife. Once she gets tired she asks Ayumi to play another game with her: find three things for her and she will tell Ayumi a secret. Once Ayumi finds all three things she finds her inside girls' bathroom. Yuka tells about how she loved her brother and how she hates Naomi, at which point Ayumi realises that the spirit is Yuka. Yuka then says that she'll like to kill her, but Ayumi dodges her attack. Then Yuka gets a better idea: call Yoshiki to kill her. Ayumi runs away from the bathroom and with the girl in red's aid runs to the next floor.
Yuka appears in the end of the chapter along with Yoshiki as Ayumi calls then out for the exorcism. It fails and Yoshiki starts yelling at Ayumi. Yuka then walks towards Yoshiki and gives him an idea to call Satoshi along. They both disappear, leaving Ayumi crying.
She appears along with Yoshiki and Satoshi and start torturing Ayumi, but they are all interrupted by Sachiko appearing and using the magic of the book to make them disappear. Ayumi later finds her inside the Corpse Pool and apologises, giving her the scented beads. After Ayumi comes back to apologise to Satoshi, she appears and they all go back to the gravesite where they bury the book. They all say their goodbyes as Ayumi leaves the school. After that Yuka's soul can finally rest in peace.
