Death end re;Quest is a gripping role-playing game that blends elements of reality and the virtual world. Players follow the journey of Arata Mizunashi, a video game programmer who receives a desperate email from his missing colleague, Shina Ninomiya. To his shock, Arata learns that Shina is trapped inside their abandoned creation, World's Odyssey (W.O.D.), and is the only player navigating the game's treacherous landscape.

As Arata dives back into the code of W.O.D., he discovers that the game is now overrun with bugs and glitches, making it a perilous environment. With her only chance of escape hinging on completing the game, Shina must unlock the perfect ending that boasts a mere 1% success rate. This journey introduces a variety of NPC characters, blurring the lines between humanity and artificial intelligence, and creating a narrative that challenges perceptions of reality.

Players will need to navigate between the real world and the game, uncovering hidden treasures and solving intricate mysteries to help Shina find her way back to reality.
