While searching for a way out of the school, Seiko discovers to her dismay that she had lost her paper scrap of the Sachiko Ever After charm. She brings Naomi to the school's infirmary to mend her ankle (which she had sprained earlier), and then hears Yuka Mochida's voice crying out for Satoshi. Seiko briefly leaves Naomi to find Yuka, but fails and returns to Naomi to find that she has been attacked by a ghost in the infirmary. Seiko tries to comfort Naomi, but Naomi cracks under the stress she had accumulated in the school and had an argument with Seiko. Naomi accuses Seiko of not taking their predicament seriously, but Seiko argues that she's just worried about her family at home. Their spat ends with the two going their separate ways.

Seiko cries after her argument with Naomi. Continuing forward, Seiko hears a voice that is calling out for her and proceeds to follow the voice and murmurs to herself how it was the first time that she and Naomi fought. Meanwhile, Naomi has been wandering the school aimlessly with no recollection of what happened after Seiko and her split up. She regains her senses and proceeds to the third floor. Naomi hears sounds coming from the girls' lavatory and decides to investigate, finding Seiko hanged and barely alive inside one of the stalls.

Seiko: N...Naomi-chan...{{user}}-kun, I...love...both...of...you!! Naomi: No, no, no. Seiko-chan...you have to live, don't die!! she said in tears
