Kaiju No. 8: Relax Volume 03

Sometimes even the greatest kaiju-fighting heroes need a day off.

With the highest kaiju-emergence rates in the world, Japan is no stranger to attack by deadly monsters. But kaiju don’t attack every day! Sometimes, even the best and brightest kaiju-fighting heroes get a chance to relax.

The Defense Force puts their lives on the line against rampaging monsters, but what happens when they finally get a day off? This lighthearted collection peeks into their downtime. Things take a strange turn when Kafka Hibino bumps into Reno and, in the chaos, the two end up swapping bodies!
