They reveal the killer to be Hitsuki Yuri, she had overheard them talking about the peeping incident while hiding in Hisashi’s room after bludgeoning him. She gave herself away when she laughed at Kyu and Kinta, because normally one would assume that they got into some sort of fight like the others did, but instead she laughed at them because she knew what really happened even though no one else didn’t. They then reveal the dying message left behind by Hisashi, it was the stack of documents that was found scattered in his room. As it turns out Hisashi had written the name of the culprit on the side of the documents and purposefully scattered them onto to the floor so that the message wouldn’t be destroyed by the killer. When the documents are stacked together the name Hitsuki is revealed. However Hitsuki claims that she and Hisashi were lovers so it wasn’t strange that the two were in the same room. She also claims that the locked room murder is impossible to solve, therefore she couldn’t be the killer. However Kyu reveals that he has already figured out the trick, he reveals that after killing Takatobi she shut the door of the concrete warehouse while pulling a cardboard box behind it. Then using a hose, she filled the box with quick drying cement and waited for it to harden and started a fire to get rid of the cardboard box. Faced with this evidence, Hitsuki confesses and reveals that her motive was that Takatobi and Hisashi had killed Yamato because they were annoyed by him constantly protesting against their dam project. She had joined them to find proof of their wrongdoings, but instead she had overheard them talking about how they had killed Yamato. It was then that she decided to kill them for their greed and for what they did to Yamato.
