Amatsuki

Rikugou Tokidoki is an average high school student struggling in History. To improve his failing grade, he attends extra classes at a cutting-edge museum, where visitors can experience a hyper-realistic virtual recreation of Edo during the Bakumatsu period. But when the simulation starts, Tokidoki is suddenly attacked by a bizarre creature. After an unexplained incident affects his left eye, he realizes he isn’t wearing VR goggles anymore-this isn’t a simulation. He’s somehow trapped inside the virtual Edo with no way to escape.
