Summary
Rohan is informed that the president of Morioh University of Information and Communication Technology had died, and so he visits the university for coverage. He meets Shohei Tsuchiyama there, the architect who was in charge of the new school building's construction. Rohan gradually becomes dissatisfied with the man's aesthetic sense and professionalism, as he was only obsessed with symmetry.

As Rohan brings this up to him, the architect does not listen and informs Rohan that he is now trapped in the multipurpose hall on the fifth floor of the new school building, which is his masterpiece and the president's death site. Rohan immediately tries to escape but is also attacked by a mystery that seems to have killed the president there.
