Mirai Nikki -13 Ninme no Nikki Shoyuusha-

This game has a completely new story under the original author - Sakae Esuno's - supervision, taking place midway through the original series.

Now another survival game will be imagined! By the God of Space and Time, Deus's, power, the once gone diary owners have now been revived. So once again the cutthroat survival game will unfold! Can you survive this battle royale?!

Additionally, by controlling the protagonist's actions, you can change how high Yuno Gasai, the heroine's, insanity will be, in the Yandere Operation System (YDO)! If her insanity becomes too high, she will become hard to restrain, so can you narrow down your choices to those that let you survive?!
