Keigo Kurusu (来須 圭悟, Kurusu Keigo) is the Fourth diary owner, and initially introduced as an ally to Yukiteru Amano and Yuno Gasai. As the Chief Inspector of Sakurami City's police force, Kurusu uses his "Criminal Investigation Diary" to predict the crimes that he will investigate, using its power to identify other diary owners.Keigo is a man of about thirty, with shoulder-length black hair, a bit of stubble on his chin, and green eyes (grey in the anime). Calm, cool and collected, Kurusu often acts laid-back, calmly challenging Minene Uryu when she bombs Sakurami Elementary School; this gives Yuki the confidence to face Minene himself. As his line of work brings him into conflict with often violent suspects, he strives to anticipate their actions and use their own personality quirks against them while preparing himself for the potential consequences or dangers to himself and his allies.

The Future Diary
Lonely high school student, Yukiteru Amano, spends his days writing a diary on his cellphone, while conversing with his two seemingly imaginary friends Deus Ex Machina, who is the god of time and space, and Murmur, the god's servant. Revealing himself to be an actual entity, Deus grants Yukiteru a "Random Diary," which shows highly descriptive entries based on the future and forces him into a bloody battle royale with 11 other holders of similarly powerful future diaries. With the last person standing designated as the new god of time and space, Yukiteru must find and kill the other 11 in order to survive. He reluctantly teams up with his obsessive stalker Yuno Gasai (who also possesses such a diary), and she takes it upon herself to ensure his safety. But there's more to the girl than meets the eye, as she might have other plans for her unrequited love...
