Deleted Memory

Deleted Memory (メモリー消去, Memorī Shōkyo) is the First episode of Season 2 the Future Diary anime, Fourteenth Overall.

Summary
This episode starts when Yuno is feeding Yuki some beef stew. Aru talks to Yuno through her surveillance feed, revealing he dug up the three corpses from her garden, two of which had recently had their skulls removed. When he threatens to give this information to the police unless she releases them, the stress causes Yuno to alter her memory again, rendering negotiations moot. As Kousaka uses his cell phone to post his will in his blog, it is apparently turned into a Future Diary by the Eighth diary holder, who addresses him as an "apprentice". On Aru's advice, Kousaka acts out his diary's predictions, reaching an amnesiac Yuno, a catatonic Yuki and a bound Hinata in the control room. His appearance causes Yuki to recover, recalling how Yuno abducted him to keep him safe until July 28th. Yuno places the key to Yuki's shackles on the floor and tosses Kousaka the control panel key, allowing him to free Aru and Mao. Yuno then takes advantage of Kousaka's distraction and shoots at him with a crossbow. However, Yuki, having had his key kicked over to him by Hinata, frees himself and stops Yuno by slapping her, leaving her behind when his diary predicts the imminent arrival of three diary holders, all apprentices of the Eighth.

Muru Muru's Section
Kosaka comes across Muru Muru floating in the men's hot spring, and the demon grants him a wish. When Kosaka requests a Future Diary, Muru Muru attempts to make him undergo a 'test' to prove his worth, which turns out to be jumping off a great height in Deus Ex Machina's realm. When he hesitates, Muru Muru pushes him off the side anyway. He awakes in the hot springs, convinced it was all a dream.
