Antagonist
The Swamp Demon, known as 'Numa no Oni' in Japanese, is a demon and the main antagonist in the Kidnapper's Bog Arc of 'Demon Slayer: Kimetsu no Yaiba'. Formerly a human, he became a demon and engaged in a series of kidnappings, particularly targeting beautiful girls aged sixteen. He possesses unique abilities that allow him to split into three clones, each with distinct personalities and fighting styles. The Swamp Demon is characterized by his pale skin, long blue hair with violet strands, and red eyes without pupils. His combat style incorporates the Blood Demon Art known as 'Swamp Domain', enabling him to create a pocket swamp dimension for his attacks. Despite his calm and analytical main body, he exhibits sociopathic tendencies and a deep fear of his creator, Muzan Kibutsuji. The Swamp Demon ultimately meets his end at the hands of Tanjiro Kamado, who seeks to avenge the demon's victims.
