Influenced by Keiichi's encouragement, and the fact her friends are starting to avoid doing the same mistakes again by remembering glimpses of what they could have done, Rika decides to find a way to prevent her ominous destiny by herself.

After getting a clue of the villain's betrayal, Rika tells her friends the truth behind the Hinamizawa Syndrome, and her connection with it. Meanwhile, the enemy moves on with their plan, eliminating any opposition.

Finding that Tomitake is captured, Irie rushes to escape and ends up meeting with Shion and her bodyguard, Kasai, on their way to the Sonozaki Estate. However, by accepting their help, he ends up unintentionally revealing Rika's hideout to the enemy.
