Yuusha, Yamemasu: Kenshuu Ryokou wa Mokuteki wo Miushinau na

Though his heroic deeds once saved the world, the mighty Demon Lord Leo Demia finds himself outcast and unwanted by the very people he protected. With his reputation in tatters and his skills unappreciated, Leo takes an unconventional path: joining the ranks of his former enemies to rebuild their shattered demonic army. His goal? To restore the Demon Kingdom to its former glory and prove his worth once more. This special episode takes a delightful detour from Leo's grand mission, as the Demon Army embarks on an unexpected training trip. But with a cast of eccentric demon generals and a hero struggling to find his place, what begins as a strategic exercise quickly devolves into a hilarious adventure, proving that even world-saving heroes can get sidetracked when faced with the ultimate team-building challenge.
