Background

Suzuki Mufeng was born to a wealthy merchant family near Mt. Sagiri. When a demon attacked his home, his parents died protecting him; despite being only ten years old and initially powerless, he held the demon off for more than ten minutes until Sakonji Urokodaki arrived. Recognizing his potential, Urokodaki accepted him as a disciple. 1 7

He trained persistently under Urokodaki but initially lagged behind Sabito, Makomo, and Giyu Tomioka. His breakthrough came after entering the Trans-Dimensional Space, where alternate versions of Mufeng shared memories and abilities across worlds. 1 7

Appearance

Suzuki Mufeng is a young Demon Slayer who wears the Corps uniform and frequently travels in a fox mask and haori prepared by Jigoro Kuwajima. 7 16

• Carries multiple Nichirin Swords during the Mt. Fujikasane Final Selection, enabling his Four-Sword Style. 9 10
• His Nichirin Sword changes through rainbow colors before becoming pristine white upon receiving it. 16
• Receives a fox-shaped Warding Mask with red sun-like markings from Makomo. 7
• Wears a Wisteria wreath given by Makomo when departing to study Thunder Breathing. 10

Personality

Mufeng is intensely driven to grow stronger and eradicate demons, shaped by the loss of his parents and the deaths of Urokodaki’s former disciples. He refuses to depend solely on abilities borrowed through the Trans-Dimensional Space, believing he must develop a power suited to himself. 7 8

Despite his combat focus, he repeatedly risks himself for strangers and comrades. During Final Selection, he spends the night rescuing endangered candidates; later, he treats villagers afflicted by Kamanue’s Blood Demon Art even at considerable personal risk. 8 18

He is blunt and impatient with defeatism, notably provoking a fight with Shinjuro Rengoku after rejecting Shinjuro’s belief that Muzan cannot be defeated. 21

Abilities & Skills
