In Episode 5 titled "All Good Things Come in Threes," Konoha Akisato grapples with the consequences of her time-travel adventures. She begins reflecting on her previous journeys into the past and discovers that the games she bought from a mysterious store are the key to her time travels, as they transport her to their respective release dates. Konoha decides to further test her theory, even at the risk of altering history.

Konoha chooses the game "Kanon," released on June 4, 1999, as her next time vehicle. When she opens the game, she is transported to 1999, just one month before the "end of humanity" predicted by Nostradamus. She finds that Alcohol Soft, the company she once worked for, has drastically changed—now operating from a large building in Akihabara and achieving success with their game "Horoscope."

Upon reuniting with her former colleagues, Konoha learns that Alcohol Soft has expanded its team and plans to port the successful game to a console with the help of the famous producer Ichigaya from Diamond Studio. The team is excited, envisioning a future where bishojo games dominate the market.

However, Konoha is torn. She fears her actions may have already altered history, as evidenced by missing games in her collection. Mamoru, the programmer, confronts her about her intentions and the risks of her time travel. Despite her concerns, Konoha is drawn to the thrill of game development and the camaraderie at Alcohol Soft.

As the team prepares for the console port, Konoha insists on taking on minor tasks to avoid further interfering with the timeline. She struggles between her desire to contribute to the game and her resolve to remain a passive observer.
