She is repeating the same scenario, and dies every time, thus making Kyousuke rewind time. In one of the replays, Saya and Riki face Shun Tokikaze, the antagonist of the manga Saya loved so much, which, coincidentally, Saya is the protagonist of the same manga. Using Riki as a decoy, she defeats Shun and goes to the 60th floor of the basement to receive the treasure. In a flashback, Saya reasons with Shun to let her replay her scenario one last time, and, because in the manga, the treasure was not revealed yet, requests Shun to make the treasure a biological weapon.

Riki then wakes up, and Kyousuke tells him that the Darkness Executives "jumped the gun" and that the treasure was a time machine.
