Adventuring knight Laios Touden leads a small party through a seemingly endless dungeon, a subterranean maze full of dangerous monsters and precarious traps. Through the use of advanced magic, an explorer can sometimes be resurrected, allowing them to learn from past mistakes and give traversing the dungeon another go. However, when a powerful dragon eats Falin, Laios' spellcasting sister, she sends her brother and his companions back to the beginning to save them from permanent ends. Though strapped for cash and equipment, Laios resolves to fight his way through the dungeon and rescue Falin before she can be digested by the dragon. Despite some of Laios' allies abandoning him, two remain by his side: elven mage Marcille Donato and halfling locksmith Chilchuck Tims. Due to their lack of funds, the party faces the daunting prospect of starving before being able to complete their quest. However, they find salvation in Senshi, a dwarven warrior with a penchant for cooking and safely eating defeated monsters. With Senshi's culinary expertise, Laios and his companions struggle through the dungeon while learning about gourmet dining—and each other—along the way.

After his high school graduation, Yuuki Wakura realizes it has been five years since his sister's disappearance during a "Mato disaster." Throughout Japan, mysterious entrances have opened to a dimension called "Mato"—a demonic metropolis filled with disastrous monsters known as the "Shuuki" that threaten the safety of humans. However, a new hope arose, as the discovery of a Mato fruit that grants supernatural abilities exclusively to women allowed them to fight against the Shuuki. Due to this, a new matriarchal government was formed, establishing a female organization called the Anti-Demon Corps, which caused men to fall to the bottom of society. When Yuuki suddenly finds himself in Mato, he is unable to escape on his own. But just as he anticipates a gruesome end by the Shuuki, a girl in a militia outfit appears and protects him. As the chief of the Seventh Unit of the Anti-Demon Corps, Kyouka Uzen is ambitious yet devalued by her own peers due to her power being deemed unusual. Now in a life-or-death situation, Kyouka takes the opportunity to find out the true potential of her superpower by using Yuuki: in order to defeat the Shuuki, he has to become her slave.
