Guess no one wants to see the truth.

Root Letter (stylized as √Letter) revolves around the mystery of Aya Fumino, your old high school penpal who went missing 15 years ago. On receiving her final letter 15 years late, in which she confesses to a murder, you set off to Shimane Prefecture to unravel the mystery of what happened to her. Reminiscing through previous letters from Aya, you must piece together the truth, alongside the testimonies from seven witnesses who knew her. Did she really murder someone, was she telling the truth in her letters – was she even real?

Root Letter was released in 2016 for Playstation Vita and Playstation 4 with additional releases on the PC and on the iOS and Android smartphone, developed by Kadokawa Games and published by PQube for North American and European Audiences. This is the first game for KG's planned "Mystery Adventure Game" series, with RL being first in line. What makes this unique is that it's one of the few Japanese-made VN games that reflects on places outside of Tokyo, especially Matsue since it's the hometown of KG's president Yoshimi Yasuda.


An unknown live-action project based on the game is scheduled to be produced by Perfect World Pictures. On August 2018, Yasuda announced that two games are in in progress, named Root Letter: Last Answer and Root Film.

Last Answer is an expansion to Root Letter, using live-action scenes, actors and visuals as an option while having scenes that further explain the endings, released in Japan in December 2018 and worldwide in 2019.note 

Root Film will serve as the game's sequel, still set in Shimane Prefecture with a 2020 worldwide release for the Playstation 4 and the Nintendo Switch.


Tropes presented by Root Letter:,

  • Anti-Frustration Features: After beating the game once, you can skip chapters 1-7 after answering Aya's letter, as chapter 8 is where the common route ends.
  • Bad Ending: Three out of the five endings can definitively count as bad with the protagonist dying in one, being institutionalized in another, and tormented by Aya's ghost in the third. The fourth is a Bittersweet Ending at best, in which Max just misses his pen pal by one day and then moves on without ever meeting her.
  • Bittersweet Ending: The epilogue of the "Princess of Himegamori Forest" route, it's one of the few ending where Max Gets The Girl, but the girl in question had tormented and even murdered her friends for revenge.

  • Everyone Dies: In the "Cursed Letter" ending.
  • Evil Old Folks: Dr. Fumino, in some endings.
  • For Want of a Nail: If the group of friends hadn't randomly stopped at Dr. Fumino's house that one rainy day, it's likely the events of the game would've never came to pass and things would've turned out very differently for everyone.
  • Happy Ending Override: Averted in the "Government Plot" epilogue, the initial ending has Max institutionalized while everybody else being captured or in the plot, the epilogue ends with Max & his friends recovered their memories and become heroes.

  • Multiple Endings: There are five in total, all of which have their own set of two letters and chapters.
  • Bond of Marriage: Upon meeting Shiori's friends at the lake, Max finds them to be tight-lipped and has to work the whole story out of them, whereupon they reveal mistakes they made with treating her, and why they refused to tell Max anything at first. Max asks where Shiori is now, to which he gets told they don't know. Four Eyes threatens suicide to bring everyone to the lighthouse, where he gets everyone to talk about their dreams and reminisce. The group then goes to see Dr. Fumino and, after asking, are informed that Shiori was listening to them speak to him. The group makes up with her, and it starts raining. Shiori says it's a destined meeting in the rain (enishizuku) to Max. In the epilogue, he moves to Matsue, and he and Shiori prepare to get married. All the remaining loose ends are tied up, as well.
  • Crossing Paths: After finally getting the story from Aya's - now known as Shiori - friends from high school, Max prepares to leave Matsue, but not after asking Four Eyes where Dr. Fumino is, as he's Max's lead to Shiori. After helping the rest of the group track him down, Four Eyes tells Max where Fumino is, and they visit him. Fumino then tells them that they missed Shiori by a day, and she's off to work to improve Africa's health care system. Much later, Max gets a letter from Shiori, saying that while she heard from Fumino that he and her classmates tried finding her, they won't be able to meet.
  • Cursed Letter: Having found out that Aya died and that Max now knows who Shiori is, the curse takes effect on the group of friends.

The group meets Dr. Fumino, who reveals that Aya's spirit takes her writer and penpal with her still ongoing curse, with Max being the sole exception.

The epilogue has a character known as Lettuce write a letter addressed to Aya Fumino, showing that the curse is still ongoing.
  • Government Conspiracy: Shiori has been discovered to be removed from all publications, and the more they think about it, the less her friends can remember anything about her. After getting Shorty's yearbook (which he had sold to a store when he needed money, and thus was overlooked and uncensored) and confirming Shiori exists, the group heads their separate ways for the day. The next day, Max and Shorty walk around town, are stalked by men in black, and go to the UFO lab to escape. Shorty remembers a UFO crash at the lighthouse, and the entire group is lured there by the men in black, where they are captured. The rest get their memories wiped, but Max escapes, learns the truth, is knocked out again, but drops a letter revealing the truth out the transport car window he's in when he wakes up.

Shiori acts much more like Aya than in other routes, and in her "suicide", she ends up possessed by Aya's spirit, who claims Shiori is dead and she is Aya. Yoshie then reveals that she merely adopted Shiori, and she's really the Fuminos' child. The next day, Yoshie calls Max and says Aya has returned, and by the time he arrives at her apartment, she suffered a heart attack and is taken to the hospital. After seeing sightings of a strange woman throughout the day, the group learns the location of Dr. Fumino and visits a strip club in the nursing home. He reveals the past, including that Shiori was being possessed by the psychopathic Aya. He then leaves, passes away that night, and Max returns to Tokyo. Several days later, Max opens his own office like he dreamed, gets a letter from Aya, and laments that he, too, is still being targeted.

  • True Ending: As is common with many visual novels, requires at least one playthrough to be unlocked.
