REDLINE is a sci-fi romance visual novel set in a near-future coastal city in southern Japan where gifted individuals can perceive, interpret, and influence human emotions — abilities now at the center of scientific research and corporate ambition.
You play as a university student with the rare ability to perceive emotional connections as red threads. As you become entangled in a secretive research program and drawn toward five distinct love interests, your choices will shape not only your relationships, but the fate of society itself.
Souta Aihara
CA: Kieran Regan
Souta used to look out for you long before either of you knew where life would lead. After years spent apart, that hasn’t really changed. He has always been a constant in your life, even when distance turned him into an edge case and timing pushed him out of context. Now that the parameters have changed, you’re stepping into the next chapter together. Almost like before…
Rei Minzuki
CA: Corey Wilder
As a martial arts ace with a laid-back demeanor, Rei has earned his place as Redhaven University’s campus favorite without ever appearing to try. Considering how little effort he seems to invest in his studies, one can’t help but wonder how he ended up at RHU at all. Then again, it hardly matters.
Leiv Kazama
CA: Jimmie Yamaguchi
Whether in academic circles or within the boardrooms of the country’s leading tech corporations, the name Leiv Kazama is hard to overlook. At twenty-seven, he stands at the intersection of research, power, and responsibility. A junior professor by title, a CEO by profession, and a man whose decisions tend to shape more than just his own future.
Takuma Shinonome
CA: Brian Timothy Anderson
Fresh out of medical school yet already deeply embedded in the research halls of SYNEVIS, Takuma is far more at home in the quiet solitude of his laboratory than in crowded rooms. Between the infimum and supremum of light, human emotion registers as chromatic outliers — patterns he can observe with precision, though not always interpret.
Aziel Viré
CA: John Patneaude
Following in the footsteps of his uncle who once led SYNEVIS, Aziel now stands at the helm of the institute’s future. Where his predecessor earned loyalty through trust, Aziel, it seems, prefers something more reliable. After all, when you understand the thread that moves a heart, guiding it becomes almost effortless.
Planned for the full release:

Note:
The full scope of REDLINE, including voice acting, additional features and content such as backgrounds and music, as well as further possibilities like an animated opening and localization, will depend on the success of a Kickstarter campaign following the demo release.
REDLINE is developed by a small independent team based in Germany, led by Marleen gollan (Moteru Games). Character art, additional game design input, and voice direction are created and provided by Moona and Amalia, forming the core team. The project is further supported by contributors across background art, music, and voice acting.
