Yuno and Yuki are picked by Deus Ex Machina. He is the God of Time and Space. They take part in the Diary Game. Which is a deadly fight between them and ten other people. Each person gets a Future Diary. These are special books that can tell the future. The last person alive becomes the next god after Deus. Yuno is the Second Diary Holder. Her Future Diary is the Yukiteru Diary. It is a stalker diary. It gives her clear details about what Yuki is doing every 10 minutes. When it works with Yuki's Random Diary, they can fix the weak points in both diaries.

In the anime adaptation, She is voiced by Tomosa Murata in Japanese, and by Brina Palencia in the English version. In the live-action adaptation, Ayame Goriki portrays a different, reimagined version of her.

 Concept and creation 
 Development 
Yuno is named after Juno, an ancient Roman goddess who represents love and marriage. In 2009, Sakae Esuno, the author of Future diary gave an interview. He said he made Yuno a yandere character to make it hard for Yuno and Yuki to work together as a team. He said Yuno is one of the problems that Yuki must face later.

 Characterization 
Yuno is a young girl. She has pink eyes and long pink hair. Her hair is tied in two pigtails. The front parts have red bows. The back parts have no bows. She often wears a blue shirt with a ribbon on the chest. She also wears a blue skirt and high socks. Her clothes change sometimes in the story. Yuno has two sides to her personality. Around Yuki, she is sweet, like a girl, and sometimes shy. But this hides her dark side. She can be cruel, cold, and smart in a bad way. She does not care much about hurting others to help herself and Yuki survive. She uses violent ways that are often sudden and cruel. These ways usually cause bloody deaths. The deaths are of Diary Holders or their helpers. This makes her a yandere.
