A nostalgic dark fantasy set on a glamorous resort island. An easy-to-play romance text adventure: this title is a "text adventure game" in which players progress by reading the text displayed on the screen. The choices selected during the game change the affection levels of the characters. The following story also changes, allowing you to enjoy independent stories for each character. This title uses Live2D character expression, and the characters behave expressively during the story. It also includes features that make it easy to focus on the story even during short play sessions, such as explanations of in-game terms (dictionary) and a skip mode for scenes already viewed. Step away from everyday life and experience a brief vacation and a wonderful journey with this title. The 3rd title in the LicoBiTs project: LicoBiTs is a game brand by Broccoli and TIS Creation. Created to provide high-quality story experiences for fans of otome games, the brand released the first project "Utakata no Uchronia" in April 2024 and the second project "UN:LOGICAL" in January 2026. While both are basic text adventures, they feature character expression using Live2D and a wide variety of visuals, and have received support from many fans. For this 3rd title, illustrator Oyo handles character design and original artwork, while Eri Ichino of Kazura Honpo handles the main scenario, delivering a new story experience where nostalgia and mystery coexist.
