Start of the Fifth Alice volume and also start of a new 2 volume series — A Diffusion Disease by Oda Hideji.
It’s presumambly Hideji’s masterpiece, or so people say. There is no real way to give it a proper summary, you are just gonna have to read it. As GGpX himself noted when being asked for a comment: “Can’t really think of anything tbh.”
It’s Oda Hideji just read it, don’t be difficult.
