Ep. 7: Reisuke's diary attempts to kill Yuki and Yuno but fails as they uncover his identity.

Reisuke’s Fifth Diary tries to assassinate Yuki and Yuno, who realize he is a diary owner. Yuno pursues Reisuke with a hammer, accidentally knocking out Rea. Discovering Reisuke mailed his diary to himself, Yuno has Yuki intercept the package, but Yuki falls victim to a poison gas trap inside. Reisuke challenges Yuno to hide-and-seek in the gas-filled house, offering an antidote for his capture. Yuno evades several traps but is eventually cornered. Yuki intervenes, injuring Reisuke with a dart, allowing Yuno to finish him off. Both collapse before administering the antidote. Minene, informed by Keigo, arrives to save them. As she leaves, she tells Yuki that killing Yuno sooner is better and declares she will be his worst enemy.
