The Future Diary - Season 1 Episode 20 Transfer Data

Despite Aru's revelation, Yuki declares his trust in Yuno. Balks connects Kamado's server to HOLON, a supercomputer which holds user accounts of every citizen of the city, making them his apprentices. Uryu tries to attack Balks, but his diary lets him turn the tables. Nishijima, who's fallen in love with Uryu, comes to her aid and destroys the supercomputer. However, it turns out to be only one part of the whole, and Balks' plan is put into motion. As Aru sends Hinata, Mao and Kousaka to help Uryu and Nishijima destroy the remaining parts of HOLON, Uryu figures out Balks' diary can read the predictions of all other Future Diaries. Deus reveals to Uryu that Balks helped him design the Future Diaries, wishing to grant divine power to the human race. Uryu, Nishijima, Hinata, Mao and Kousaka storm HOLON's location, overwriting their diaries' predictions to confuse Balks. In response, Balks makes use of his secretary's diary and manages to capture Hinata, Mao and Kousaka, as well as injure Uryu and kill Nishijima. Uryu is saved by Yuki and Yuno, who've used her as bait to get to Balks.
