Kamado Ueshita is the Eighth diary owner. A large, rather unconventional-looking woman, Kamado runs the "Mother's Village" orphanage in Sakurami City. She has raised orphans for at least fourteen years, including Marco Ikusaba, Ai Mikami and Orin Miyashiro. As the least harmful of the Survival Game's participants, Kamado has no interest in becoming God; instead, her orphans fight to protect her from the other diary holders. Kamado is a portly woman with strange, almost cartoon-like proportions; her arms and legs are disproportionately small compared to her body, while her head is disproportionately large. She has short black hair, green eyes, and large pink circles on her cheeks. Her upper lip has a slight cleft, which makes her mouth resemble a cat's. She wears an orange dress with a white chef's hat and a matching apron. Having cared for and raised numerous orphans over the years, Kamado is a doting motherly figure beloved by all of her orphans, who form an army to fight in her stead during the Survival Game. Kind, caring, polite and pacifistic to a fault, she is perhaps the most sane and least violent of all the diary owners, and the only one aside from John Bacchus who does not engage in physical combat. While Kamado has no interest in becoming God, her children will do anything to protect her and wish for her to win the Survival Game. It is implied that Kamado would accept the mantle of God for the orphans' sake if she happened to win the Survival Game; if she does, she wishes to make the world a better place for children so they would not have to worry about things. She loves children in general, showing concern even for those not in her care like Yukiteru Amano and Aru Akise. She even proves willing to forgive Yuki for attempting to kill her (and allowing Yuno Gasai to do it instead), simply asking him to make a better future for the children before passing away without grudges or regrets.

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...
