High schooler Hayase Nagatoro loves to spend her free time doing one thing, and that is to bully her Senpai! After Nagatoro and her friends stumble upon the aspiring artist's drawings, they find enjoyment in mercilessly bullying the timid Senpai. Nagatoro resolves to continue her cruel game and visits him daily so that she can force Senpai into doing whatever interests her at the time, especially if it makes him uncomfortable. Slightly aroused by and somewhat fearful of Nagatoro, Senpai is constantly roped into her antics as his interests, hobbies, appearance, and even personality are used against him as she entertains herself at his expense. As time goes on, Senpai realizes that he doesn't dislike Nagatoro's presence, and the two of them develop an uneasy friendship as one patiently puts up with the antics of the other.

Kazuma Satou, former NEET and current reincarnated adventurer, finally returns home after the incident at the Crimson Demon village. He is joined by his ever-reliable companions: self-absorbed goddess Aqua, one-trick pony arch-wizard Megumin, and masochistic crusader Lalatina Ford "Darkness" Dustiness. Following their recent exploits, the party is one step closer to vanquishing the Demon King and his armies—a terrifying task that Kazuma is eager to ignore for as long as possible. Things, however, are not going as smoothly as the group would like; they are constantly racking up debt, getting sidetracked during missions, and falling into traps due to their recklessness and eccentricities. As the party struggles with their perennial issues, they receive an invitation from a princess interested in hearing tales of the group's "heroic" deeds. Darkness' pleas to refuse the invitation only fire the others up to accept it, marking the start of yet another uncanny adventure with unforeseen consequences.
