is a Japanese adult visual novel developed by Cube, a brand of Cuffs. It was originally released on September 30, 2011, for Microsoft Windows. Later, Alchemist ported the game without the erotic content to the PlayStation Portable. Your Diary will be released for the PlayStation 4 and PlayStation Vita. The story revolves around Tomoki Nagamine, who has feelings for an upperclassman named Sayuki Ayase. Upon receiving a diary from the library manager, he is informed by Yua that all of his happiest memories will be recorded in the diary.
The gameplay of Your Diary follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the four female main characters by the player character. The game ranked as the third best-selling bishōjo game at the time of its release. It received a manga adaptation which serialized in Hakusensha's Young Animal Island between volumes 19 and 24.
Your Diary is a romance visual novel in which the player assumes the role of Tomoki Nagamine. Much of its gameplay is spent reading the text that appears on the screen, which represents the story's narrative and dialogue. The text is accompanied by character sprites, which represent who Tomoki is talking to, over background art. Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character sprites.[1] Your Diary follows a branching plot line with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction.
There are four main plot lines in the original Windows release that the player will have the chance to experience, one for each of the heroines in the story. Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. Some decisions can lead the game to end prematurely and offer an alternative ending to the plot. To view all plot lines in their entirety, the player will have to replay the game multiple times and choose different choices to further the plot to an alternate direction. In adult versions of the game, there are scenes depicting Tomoki and a given heroine having sex.[2]
Tomoki Nagamine attempts to confess his love to an upperclassman named Sayuki Ayase; however, he does not succeed in doing so, being caught off by a sad expression on her face. In the meantime, he works alongside his crush Sayuki in the library committee. One day, after wandering into a seemingly-abandoned library, the library manager Misuzu gives Tomoki a diary called "Your Diary", telling him that the book chose him. A cute girl introducing herself as Yua—who is the goddess of happiness—comes bursting out of the book and informs Tomoki that all his happiest memories will be recorded in his diary.[3] The story mostly revolves around Tomoki interacting with the four heroines (in later versions, seven) and eventually forming a romantic relationship with one.
Your Diary is the second title developed by Cube. The game was planned to have fantasy elements incorporated in, unlike Cube's previous visual novel Natsu no Ame, which was thought by staff to be quite a realistic story.[6] The scenario was written by Inori Tanemura and Airu Minamoto.[7] In Your Diary+ and Your Diary+H, Ryoichi Futaba assisted in writing the screenplay.[8] [9] Character designs were drawn by Kantoku, who is best known for his illustrations in the light novel series The "Hentai" Prince and the Stony Cat; the super deformed (SD) art was by Suimya. Lastly, the game was directed by Naoto Sakura.
