The Demon Slayer’s Restaurant summary: Kang Cheol-ho was once the mightiest warrior summoned to another world, where he fought and defeated the Demon King after decades of war. Now, 30 years later, he finally returns to Earth… only to find it in the middle of a new crisis: the age of monster raids. But Cheol-ho is tired. He’s had enough of bloodshed, battles, and glory. So he hangs up his sword and chooses a different dream: to open a small restaurant a peaceful place where anyone can stop by, eat, and rest. As weary Hunters, broken strangers, and curious visitors walk through his door, Cheol-ho offers them warmth not through strength, but through a good meal and a listening ear. A gentle, heartwarming story about food, healing, and second chances.
