Astro King: Shoukan Yuusha dakedo Kakyuu Ninteisareta node Maid Harem wo Tsukurimasu!

A group of high school students is suddenly summoned to another world, tasked with the daunting mission of conquering a perilous dungeon as heroes. To ensure their cooperation, the summoners entice them with an irresistible promise: unrestricted access to the castle's maids. Driven by this alluring reward, the young heroes eagerly step into the unknown depths of the dungeon, unaware of the brutal challenges that await them beneath the surface. As the expedition progresses, the reality of the dungeon proves far more lethal than anticipated. One after another, Yoshitsune’s classmates fall in battle, overwhelmed by the relentless dangers lurking within. However, Yoshitsune himself was initially assessed and classified as a low-rank hero upon arrival, leading others to underestimate his true potential. Despite his inferior designation, he possesses a hidden cheat skill that sets him apart from his struggling peers. Rather than succumbing to the same fate as his defeated classmates, Yoshitsune leverages this unique ability to steadily expand his personal harem of maids. While the rest of the summoned heroes falter against the dungeon's threats, he carves out his own unconventional path to survival and indulgence.
