Far to the north of the world lies Hell's Gate, a portal formerly used by the Demon Lord to invade the human realm. Thanks to the legendary hero Shion Bladearts, wielder of Excalibur, and his loyal band of companions, the Gate was sealed off and the demonic threat was vanquished. Unfortunately, the seal was incomplete and has begun to weaken, allowing the demons to once again begin their attack. Worried about the safety of his village, selfish and perverted farmer Touka Scott dig pitfalls to defend against the demons. But fear not, for Shion is on his way to reseal Hell's Gate and save humanity! Or at least he was, because the legendary hero is dead, having fallen into one of the pitfalls Touka dug. Luckily, dealing with the dead is the specialty of necromancer Anri Haynesworth. While she can't revive him, Anri can at least salvage their quest by forcing Touka's soul into Shion's rotting body and dragging him along to Hell's Gate in Shion's place. Not wanting to be left behind, Touka's childhood friend Yuna Yunis tags along. Together, the three of them set out as what just might be the most unsuitable party to ever try to save the world!

Despite having a good reputation as one of the most seasoned guards in the local guild of Mebuki, Kikuru Madan believes he has been wasting his youth and hopes to spend the rest of it like any other person. However, his conscience prevents him from retiring at present, as he worries about the guild's future without him. Coincidentally—as if to help him find his successor—the guild's receptionist, Enome, assigns Kikuru four fresh recruits: the energetic beastwoman Hitamu "Hitamuki" Kyan, the prodigy Maidena Ange, the laid-back Toxico Dannar, and the stalwart Hanabata Nohkins. Although each of them possesses significant talents, they also display characteristics that detract from their potential—including Hitamu's extreme clumsiness and Hanabata's unintentional perverseness. As if there was not enough to deal with, the monsters outside Mebuki's walls start exhibiting odd behavior by targeting women salaciously, causing the party endless problems in more ways than one. Nevertheless, Kikuru is committed to retiring early; to achieve his goal, the guidance he gives the trainees will be absolutely essential.
