The story is set in a closed space between this world and the next, similar to a school classroom, known as "Dogma Class." It's like a "school" where humans are given the opportunity to atone for their sins before going to the "other world." Humans who get into trouble and argue selfishly are sent there. Surrounding these humans are zombies who judge their sins... The zombies, each with their own unique personality and abilities, abide by the rules of democracy and sometimes solve problems with warm-hearted encouragement and sometimes by being close to humans. Everyone has some kind of "sin" hidden in their heart, even if they don't feel that it is a sin. Between superiors and subordinates, between friends, between spouses... What will the people who have been in abusive and foul-mouthed conflicts feel at "Zombie School"? And what judgment will the zombies pass on them...?
