In a world plagued by threatening creatures known as Kaiju, Kafka Hibino aspired to enlist in the Japan Defense Force to defeat them.

“Let's wipe out the Kaiju together.”

Kafka pledged to his childhood friend, Mina Ashiro. Over time, life circumstances forced them to go their separate ways and caused him to abandon his lifelong ambition.

He found himself employed by Monster Sweeper, Inc., a professional cleaning company that specializes in cleaning up the aftermath of Kaiju battles. Meanwhile, Mina Ashiro is now the Captain of the Defense Force’s 3rd Division. As it stands, he is currently unworthy of fighting Kaiju alongside her.

At work, Kafka crosses paths with the highly motivated Reno Ichikawa. Reno’s undying determination to join the Defense Force leaves no room for failure. His perseverance reawakens Kafka’s ambition of standing next to Mina as they protect humanity from Kaiju together.

A dream frozen by time, thawed by a burning promise.

But Kafka doesn’t know that an imminent Kaiju threat is unexpectedly approaching him.
