I Swallowed the Heavenly Demon

“I Swallowed the Heavenly Demon” follows the story of Min Jae-ha, a man who once dreamed of becoming a hero but failed to achieve his ambitions. In this world, heroes are individuals who manifest the powers of heroic spirits, using them as weapons or blessings to fight against monsters. Forty years ago, three mysterious seeds fell to Earth, bringing with them hordes of monsters. Min Jae-ha works at a company investigating mineral dungeons, where one day he steps on a summoning circle, unexpectedly gaining the power of a legendary heroic spirit. However, this spirit resides inside his belly instead of manifesting as a weapon.

This unique partnership leads to a mix of martial arts training and witty banter between Jae-ha and the heroic spirit, providing a fresh take on the genre with a blend of action, adventure, and humor​
