Mirai Nikki -13 Ninme no Nikki Shoyuusha-

This game presents a brand-new story supervised by the original author, Sakae Esuno, set midway through the original series. A new survival game begins! By the power of Deus, the God of Space and Time, the once-lost diary owners are revived, and the cutthroat battle royale unfolds once more. Can you survive? Moreover, by controlling the protagonist's actions, you can influence Yuno Gasai's insanity level through the Yandere Operation System (YDO). If her insanity rises too high, she becomes uncontrollable—can you make the right choices to survive?
