Ep. 15: Deus reveals the diary server location, prompting Aru to trap apprentices at Kousaka's mansion.

Deus explains that the Eighth's diary functions as a server distributing predictions to apprentice blogs. After Yuki's diary forecasts an assault by three individuals, Aru relocates him to Kousaka's residence to lure the attackers and disable the local cell tower. Yuno interrupts this plan by cutting the power to prevent Yuki from being used as bait. While Aru and Kousaka manually shut down the tower, Yuno restrains Yuki. Marco Ikusaba and Ai Mikami corner the pair, revealing they possess the Seventh Future Diary, which operates independently of the Eighth's server. Yuki frees Yuno to confront them, but when a third apprentice ignites the mansion, Marco and Ai use their synchronized prediction abilities to overwhelm Yuno. Both Yuno and Yuki suffer injuries and lose their diaries. Later, while recovering in the hospital, the group is visited by Minene.
