- Yui experiences headaches upon seeing the house for the first time. She sees visions of the boy and girl playing together in the house.
  - She sees the the boy and girl drawing monsters, but this vision appears blurry.
  - She also has a recurring vision of the windows in the house shattering into pieces by unknown means.
- When Tezuka explores the inside of the house, Kanzaki Shirou appears in front of him.
Shinji learns that Ren is fighting in the Rider Battle to save Eri's life. Ren wishes to continue fighting, so Shinji decides to fight him.
- Asakura injures Shinji's right arm before the latter finishes transforming. The injury puts Ryuki at a disadvantage when he fights Ouja.
  - Furious with Asakura for his foul play, Knight saves Ryuki from Ouja's Final Vent. Knight declares he will be the one to defeat Ryuki.
  - In a shocking twist, Ouja takes control of Metalgelas by using a second Contract Card. Ouja now has two Contract Monsters.
    - Ouja activates Gai's Final Vent and deals a devastating blow to Knight and Ryuki.
