Do you think you are doing the right thing? Nothing was wrong, was it because of another guy? But most people think the same way as you, so it's absolutely impossible to decide what's right. If you don't know it, you'll just be hunted like a rabbit that failed to escape. It's up to you whether the opponent will be a witch of fire or a god of death ── The two geniuses, Akemi Kurennai and Kentaro Habara, confront each other over the where boys and girls disappear from the city. Waiting for the end of a suffocating brain battle that does not show each other's appearance, however, is the product of chaos and emptiness that they cannot imagine, "Rabbit Run". Can they prevent the world from being contaminated with irresistible ruin by trampling everything, spreading innocent malice without any remorse ...?

The long-awaited latest volume of Boogiepop, where important people collide!
