Japanese anime in Qiu Yi was originally a wasteland, and many hooligans raped and robbed everywhere. Later, there was an animation of a hero saving lives, which was a movie when renting a VCD.

From 265438 to 030, affected by the Third World War, a huge polluted area called "BS" appeared in all parts of Japan. "BS" was isolated into ruins with huge walls, but soon, residents appeared in this barren land. They are called "unnecessary" by people who live in "cities" and also have special abilities in cities.

The story begins with a boy named Kurrus Cyert, whose goal is to liberate "BS" from the violent rule of Simeon. In a battle with Adam Coulette, the rebel group was disintegrated, and the survivor Kurus fled into the underground waterway alone. Adam Brett, who looks like Coulette, rescued him when he was chased by the pursuer. Kurus and Brett later came to the church and met many companions. Taking this opportunity, Kurlus began to live and fight in the church.
