"Kohaku no Ibara" Kyou

Kyou stands as one of the fearsome 'Demon Kings' who dominate Tokyo's criminal underworld. As a syndicate leader who underwent ether-enhancement surgery, he wields a supernatural ability to manipulate thorned vines visible only to himself, and has demonstrated a capacity for limb regeneration that defies all logic. His abduction of Sera brought him into direct confrontation with the protagonist Miyo, establishing him as the primary antagonist who showcases the terrifying power of the 'Demon Kings' in the story's early chapters.
