Evaluation

CARTAGRA launched on Steam on June 25, 2026 as a remastered HD version of the visual novel by Innocent Grey, and the release includes the epilogue "Sacrament". The store listing notes that the Steam version is based on the 2026 console version with some minor content adjustments. The only developer posts since launch are two maintenance updates: version 1.0.0.1 on June 26, 2026 fixed bugs, and version 1.0.0.2 on July 15, 2026 improved program stability. Neither update adds new content or mentions future plans. The developer has not said whether more content will follow, and because the game is recent, there is not yet enough information to judge its long-term content outlook.

About this game

The visual novel masterpiece by Innocent Grey, the renowned creators of Kara no Shojo, CARTAGRA, is now available in remastered HD, including the epilogue "Sacrament"!

Story

Several years after the end of the war in Showa era Japan, a man travels alone on a train bound for Zushi—Takashiro Shugo, a retired police officer. Despite his retirement, Shugo is on a mission to investigate the disappearance of a well-to-do family's daughter as a favor to his former boss, Arishima Kazuma, who is currently heading the Ueno Serial Murder Case.

Upon arriving at the Kozuki residence, the site of the disappearance, Shugo is surprised to encounter Kozuki Kazuna, as she has the same face as his former lover and her twin sister, Kozuki Yura. Kazuna begs Shugo to find her sister, but their father, Kozuki Keiichiro, declares bluntly, "My daughter is already dead."

And so the curtain rises on a tragedy set in the town of Ueno, as both fiction and reality intertwine...

Branching choices

This is a multi-enidng visual novel where the choices you make alter the path of the story. As the protagonist Shugo delves deeper into both the Ueno Serial Murder Case and the Kouzuki Disappearance Case, unexpected connections between the two incidents begin to reveal themselves. The choices you make will determine the fate of the characters.

Multi-language support

CARTAGRA is presented in both English and Simplified Chinese translations with the original Japanese voice acting.

Compatible with Steam Deck and touch screen devices!
