Room 23

This is the overall twenty-fourth chapter of You-Zitsu manga series.

Summary
While the girls were waiting for their turn to go the shower, Kiyotaka was going through the students' luggage. He opens a specific bag and takes out something resembling a book. He then remarks to himself that Ibuki had acted just as he had expected.

Some time later, Suzune approaches him and asks him to go to a private place to talk. When they reach the forest, she confesses that she lost her key card. Even though she felt guilty about this, Kiyotaka said that she did her best. The two agreed to keep this a secret and she voiced her suspicions towards Ibuki. He agreed to watch her in a discreet way, since if they made a mistake she could escape. Suzune was feeling tired from her illness and asked Kiyotaka to go back to the camp first.

While alone, she could see the smoke rising up from the camp. Suzune went to see what it was about and saw that something was burning. She looked around for Ibuki and was surprised to see her there, her expression puzzled by the fire. Hirata explained that someone had set the manual on fire; Furthermore, he said it was his fault for leaving it in an easy to steal place. He was frustrated by the incidents of the past few days, but Kiyotaka came in and told him that taking blame is not always the solution. After putting out the fire, the students began to argue among themselves about the possible existence of a traitor in the class; however, they had to interrupt their discussion because it started to rain. Soon, Hirata becomes depressed and murmured to himself that it was just like the last time but soon started acting normal after Ike called out to him.

Kiyotaka notices that both Ibuki and Suzune had disappeared and decides to go to the forest. While walking, he finds some footprints, and after following them, he sees some lights in the rain. He thinks it may be two people signaling to each other, and hides behind a tree to avoid being seen. Moments later, the lights went out and the people left. After walking some more, he finds Suzune unconscious with the key card next to her.
