A Returner's Magic Should Be Special (Korean: 귀환자의 마법은 특별해야 합니다) is a definitive masterpiece of the "Regression" and "Academy" subgenres. It stands out for its intellectual approach to combat, where the protagonist wins through analytical genius and tactical leadership rather than just overwhelming mana or brute force.

The story follows Desir Arman, a survivor of the "Shadow Labyrinth"—a catastrophic disaster that wiped out most of humanity. After failing to defeat the final dragon boss, Desir is inexplicably sent back 13 years into the past, to his first day at the prestigious Hebrion Academy. Armed with a decade of tragic combat experience and a unique ability to "invert" complex magical formulas, Desir sets out to prevent the upcoming apocalypse by restructuring the academy's elite-focused system and gathering the allies he once lost.
