Dissolving Classroom is told through a series of connected short stories that follow Yuuma and Chizumi Azawa. Each story revolves around the tragedies Yuuma and Chizumi cause, mainly through Yuuma's apologies, which he is actually using to connect with the Devil.[5] Due to the "evil electromagnetic waves between him and the Devil,"[6] Yuuma's apologies, which are usually a result of Chizumi's behavior, make people's brains melt and his compliments cause people to become permanently and horrifically disfigured. Drawn in a Baphomet-esque style, the Devil is repeatedly brought up and is the main source of evil and horror in the manga.[7
