Instead, he cleans up the remains of the slaughtered kaijuu after they are defeated by valiant soldiers—including Mina, who has successfully achieved their shared goal. Upon meeting his new coworker, Reno Ichikawa, Kafka faces a mirror of his past self: an ambitious young man whose one desire is to fight as a member of the Defense Force. Unfortunately, the two are soon involved in a freak encounter with a rogue kaijuu. Though Kafka demonstrates his innate heroic nature and rescues Reno from certain doom, he is left gravely injured. While both men recover in a hospital, Kafka is seemingly attacked by another one of the beasts. As a result, he gains the ability to transform into a humanoid kaijuu with the strength and powers of the massive monsters menacing Japan. Dubbed "Kaijuu No. 8" by the military, Kafka resolves to use his newfound gifts for the greater good. Tied together by mutual respect, Kafka and Reno set out to join warriors like Mina at the forefront of the Defense Force.

Living in the slums of a wealthy town, Rudo and his foster father Regto try to coexist with the rest of the town's residents, but Rudo despises the wastefulness of the upper class. Ignoring the warnings from those around him, Rudo regularly rummages through the town's garbage in search of anything useful or valuable to save from the "Abyss"—a massive hole where anything considered trash is dumped, including people. Rudo's biological father was one such person, having been thrown into the Abyss after he was accused of murder. One day, after running into a mysterious figure on the way home, Rudo returns to find Regto's dying body on the floor.

In order to get his revenge on the one who killed Regto, Rudo reluctantly becomes a Cleaner to fight his way back up and out of the Abyss.
