7'scarlet

7'scarlet is a visual novel in which the player reads through the story, and makes choices that affect the direction of the story; they need to replay the game multiple times and take different paths to uncover the whole story. The player character has a default name, but the player may change it if they wish; if they use the default name, dialogue mentioning the player character by name will be voiced. Throughout the game, items are added to the player's "TIPS" glossary, including explanations of terms and background stories for characters and locations.

The game follows Ichiko Hanamaki, a college student whose brother has disappeared in the town of Okunezato a year prior to the start of the game. She and her childhood friend Hino Kagutsuchi find a website discussing mysteries surrounding the town, which will host an offline meetup in the town during the summer; Ichiko and Hino go there to investigate Ichiko's brother's disappearance.

7'scarlet was developed by Otomate and Toybox Inc., and was directed and written by Deadly Premonition producer Tomio Kanazawa, with character designs by Chinatsu Kurahana, and music by Yuki Sugiura. The opening theme, "World's End Syndrome", was performed by Kaori Oda and composed by Myu; the ending themes "Me no Mae no Hohoemi", "Koboresou na Tsuki" and "Itoshisa o Daita Hana" were performed by Mao, Oda, and Haruka Shimotsuki, respectively; and the insert song "Lovesick" was performed by A-TO and Auk Zero.

The town of Okunezato was based on the real-life town Karuizawa; Kanazawa had wanted to set a game in the actual Karuizawa, but was asked to make it a fictitious place, so he took artistic liberties with the location and changed it to a crescent-shaped town surrounded by forests and rivers; some specific areas remained largely unchanged, such as Okunezato's main street, based on the Old Karuizawa Ginza Avenue.

Famitsu gave the game their Gold Hall of Fame award, saying that they enjoyed its mystery theme and how it was well integrated with the otome format despite how it was unusual to see the two elements combined. They also enjoyed learning more of the mystery on each new route they played through. 4Gamer.net enjoyed the music, saying that they liked the sense of mystery, and that the song "Through the Woods" in particular gave them goose bumps.

7'scarlet was the 16th best selling game in Japan during its debut week, selling 3,128 copies.
