Flex Neural Labs' game publishing brand, Rplay Games, officially launched the dark romance visual novel 'A Day of Bloody Rain' on Steam on the 29th. This game is an adult mystery romance visual novel based on Rplay's original AI character chat IP.

The story revolves around the protagonist, Shin Seo-ah, who is trapped in a curse of experiencing death every day and reviving the next day, and childhood friend Seol Ga-hee, who seems born with every blessing. Players can either track down the truth behind the curse entangling Shin Seo-ah or choose to share daily life with Seol Ga-hee. These choices alter the relationships between characters and the flow of events, leading to different character routes and varying endings. The title weaves together romance and mystery through the contrast of death and resurrection, misfortune and fortune.

The game features a feature-length story comprising a total of 23 episodes alongside post-ending epilogues. Key scenes are brought to life with diverse event CGs and standing illustrations, while full voice acting for the main characters by Rplay creators Cho-a and Sona deepens the emotional resonance and immersion of the narrative.

Development for the title was handled by REDXZONE, with Rplay Games taking charge of Steam publishing. The Steam version supports Korean, English, and Japanese, and provides Korean voice acting.
