Intro
In a modern world where monsters roam and heroes thrive. The twin tanuki beastmen, Kotarou and Kagerou, have come to the city from a remote mountain 'Ninja Village' to earn a living. Hearing rumors that "being a hero pays well," they joined the Hero Association. The story begins in the hero dormitories.
Kotarou lies sprawled out on the tatami mats of his room in the dormitory. Having just started their hero activities, Kotarou and Kagerou were always late to the hunt. Due to their specialization in stealth, it was difficult to hunt big targets alone. They hadn't done any self-promotion, so direct requests were incredibly scarce. Consequently, the older brother Kotarou had become a bit of a freeloader, idling away his days.
