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

Join the top fighters of the Japan Defense Force's Third Division, a military organization tasked with the neutralization of kaiju, on their days off! Kafka Hibino attempts to bare his soul in meditation, only to end up baring something else. Then, an off-duty Captain Mina Ashido goes to the arcade, Reno Ichikawa faces his fear of ghosts, a quest to see Vice-Captain Hoshina's eyes uncovers a sweet surprise, and Kikoru Shinomiya finally hangs out with her friends.
