Ep. 3: Riki dan Saya turun lebih dalam sementara Saya mengungkapkan perasaannya sebelum menghadapi loop mematikan.

Riki and Saya continue to the fifth basement after working together to pull a lever hidden in the ceiling. After they encounter a moving statue, Saya uses a sword that Riki found to destroy the statue. Saya sprains her ankle, and Riki carries her out, much to her embarrassment. Due to this, Saya decides to confess her feelings to Riki while trying to get a kiss from him. Although Riki is initially caught off guard, he then tells her to close her eyes, answering her confession back with the kiss that she wanted. As they bypass more obstacles and reach the sixth basement, Saya wishes that the secret treasure turns out to be a time machine so she can meet Riki all over again. She asks him out on a date if the mission ended successfully, which he promises back. They encounter Shun Tokikaze, the director of the Darkness Executives, before Saya faces Shun alone in a battle. However, after she dies, a screen displays "game over". This game restarts, claiming it to be her 99th or 100th time, and the whole journey repeats with her asking Riki to run down the school hallway. (Source: Wikipedia)
