Rank F in the Real World: My Life as the Demon King's Roommate.

Artur Sato was the Chosen Hero, the warrior destined to end the reign of the Demon King Belial. However, after months of an epic journey, Artur arrived at the Dark Castle only to find absolute silence: no orcs, no traps... just an empty throne. While returning home in a daze of confusion, a runaway carriage struck him, sending him straight into our modern world. Now, the legendary Hero must share a 40-square-meter apartment with Saint Maria and the Demon King himself. This novel is a Reverse Isekai created with one goal in mind: to make you laugh by breaking every cliché of the genre. Here, you'll see what happens when characters try to apply medieval logic to modern life—from shouting the name of an attack before launching it and smashing vases expecting items to drop, to trying to win daily arguments using "the power of friendship." While the Demon King tries to survive as an accountant in a debt collection agency and the Saint searches for her place in the world, our Hero will discover that adapting to Earth is the hardest quest he has ever faced. Author’s Note: This is a lighthearted read designed for relaxing and killing time. If you enjoy the series, please leave a comment!
