Detention at the Hero Academy

Detention at the Hero Academy is a LitRPG progression fantasy novel set in a magical academy with a game-like System overlay. The story follows Daniel Harmon, a fired history teacher from Earth who is isekai'd to Kingsreach Academy and assigned the obsolete [Guidance] class. Tasked with mentoring Homeroom 114-a "discard" class of students with non-combat abilities like cartography and minor luck manipulation-Daniel must help them level up to survive the lethal Ranking Exam. The book features weak-to-strong progression, unique class evolutions, LitRPG stat blocks, and a reluctant mentor protagonist fighting against a flawed, bureaucratic magical system to stop an ancient Blight.

A fired history teacher. A homeroom of magical rejects. A system that measures all the wrong things.

Daniel Harmon went to sleep in New Jersey after losing his job and woke up falling into the courtyard of Kingsreach Academy for Heroic Cultivation. Assigned the [Guidance] class-a support role so useless it hasn't been chosen in three centuries-Daniel is tasked with advising Homeroom 114, the lowest-ranked "discard" cohort in the entire school.

His students include a Cartographer nobody listens to, a Beastspeaker bonded to a barn cat, a Herald who refuses to buff, a Squire who runs errands, and a Herald of Minor Miracles who considers not stubbing his toe a major victory. The System says they are dead weight. The upcoming Ranking Exam will almost certainly result in their expulsion.

But Daniel spent twelve years fighting broken educational systems on Earth, and he isn't about to let a magical interface tell him his students are worthless. By ignoring the combat leaderboard and focusing on the unique, invisible strengths of his team, Daniel begins to unlock class evolutions that haven't been seen in generations.

They'll need every edge they can get. A localized, magical Blight is hollowing out the Academy from the inside, and the prestige-class heroes are completely blind to it. To save the school, Homeroom 114 will have to prove that the most powerful abilities are the ones the System forgot how to measure.

Detention at the Hero Academy is a slow-burn LitRPG progression fantasy featuring detailed stat blocks, clever class synergies, and a snarky, reluctant mentor who fights bureaucracy with sheer stubbornness. Perfect for fans of magical academies, weak-to-strong underdog stories, and system-based worldbuilding.
