Root Letter

Root Letter is a visual novel and investigation game about a murder tied to a 15-year-old correspondence. When a letter from an old pen-friend arrives 15 years late, you learn she was involved in a murder before she disappeared. You travel to her hometown and use her past letters as clues to investigate the case and uncover the truth.

Investigate in Shimane

You explore rural Shimane, visiting real-world locations and interviewing suspects. You search for clues, present evidence and examine your surroundings. In Interrogation mode, you use evidence to catch characters in lies.

Letters and choices

As the investigation spans 15 years, you make difficult choices and question whether your pen-friend was telling the truth—or even existed. The game has five different endings, each with a different route.

Art and soundtrack

The visual novel artwork is by Minoboshi Taro, and the soundtrack is composed by Takashi Nitta. Noriko Hidaka provides the lead voice role.
