A correspondence from fifteen years ago
In the letter, the pen pal mentioned being involved in a murder case and then disappearing without a trace. The protagonist arrives in her hometown and cross-relates past letters with real-life people and places. As the visits continued, the question was no longer just where she had gone, but also whether the life described in the correspondence back then was credible.
Explore and inquire
Players can move around Shimane, investigate the environment, gather clues, and present evidence to relevant characters. Dialogue not only provides context but also helps uncover contradictions within the narrative; Past letters and immediate testimony together form the basis for judgment. The scenes include real locations, allowing the survey route to blend with local scenery.
branching and composing works
The game features five different endings, with mysteries unfolding from different directions. Character art was created by Taro Minoboshi, music composed by Takashi Nitta, and Noriko Hidaka participated in voice acting for the main characters. In 2017, the Steam version was released; A subtitle version titled 'Last Answer' was later released.
Seven other survey subjects besides classmates
The exploration begins at Matsue Manor by Lake Shinji: the proprietress Haruka Yamamoto is familiar with the area, and the maid Tomoko Sakata is willing to help visitors. The owner of Shinzai-an, Genkichi Uno, takes care of the protagonist, while Eiji Nakamura, owner of Nakamura Bar, acknowledges the staff member Notsu. Arisa Sasaki is Riko Sasaki's daughter and performs in a local theater troupe; Yuka Fukui supports her fiancé Omori in opening a store. During the investigation, these life relationships come into view alongside characters from old letters.
Three types of investigation stages
The process consists of three repeated parts: tissue, exploration, and follow-up. The paper section returns to ten letters from fifteen years ago, the exploration section searches for seven classmates in Shimane who know the truth, and some are pursued and confronted with them, gradually correcting misunderstandings and getting closer to the truth behind the letters.
Original version and additional version
The Japanese PS4 and Vita versions were released on June 16, 2016, with the DMM Windows version released on March 31, 2017, and the Steam version on July 7, 2017. On December 20, 2018, Last Answer added a live-action mode and an explanation section, while retaining the original illustration mode; Its live-action actors and newly added main character voices are recorded separately. The original PREMIUM bonus includes 30 tracks, credited to Takashi Nitta and Takayuki Nakamura, and includes versions not included in the game.
Respond to how it affects relationships
During recall communications, players select words from the options to form a reply, and Ami's affection level changes with the reply. At the end of each letter, a question is asked; the reply not only revisits the old text but also determines the distance between the two and influences the story's final direction.
Replies and letters that stray from your heart
If you repeatedly give answers that don't match Aya's wishes, the letters you receive may suddenly switch to letters with skull or alien designs. The official website links this feedback to the story's direction, and repeated correspondence is also used to approach her hidden sincerity.
The scale in Max mode
Max mode activates during the climax of the catch-up phase. Players coordinate the vertical changes on the scales on both sides to convey their feelings with appropriate emotional intensity, attempting to elicit the other person's hidden true voice.
Conversations and proofs in the case of reason
The official website uses Riko as an example: first start the topic by using her past stage name, then show the copied class roster to prove she and Aya are in the same class. She then continued to use materials obtained from exploration to prove her previous entertainment activities, gradually advancing the debate.
The distance caused by magazine photos
Riko originally wanted to become an actress and was first invited by a photographer, but only Ami's photo appeared in the magazine. As a result, she gradually distanced herself from Aya and severed ties after an incident before graduation.
From the letters, I read the sincerity of an old friend
Once Riko agrees to listen to him, the protagonist shows Ami's old letter. In the letter, he sincerely thinks Riko is very cute and will become an actress in the future; After reading about this support, Riko recalled the close times they once shared.
Last Answer: The range of real-life reproduction
Last Answer's drama mode uses live-action to recreate ninety characters and all locations in the game. The original illustration format remains intact, and players can choose between two visual styles.
Last Answer: The subsequent entrance to the Curse Letter route
The "Curse Letter Route" Chapter begins with an urban legend of recipients dying one after another. A reporter arrives alone in Shimane, meets a woman claiming to be related to Ami, and is guided by her into a declining Western-style mansion.
