Long

Long inhabits a corpse crowned by a pair of red horns and framed by messy, shoulder-length hair in a dark purplish red. Her stare is striking, with red irises ringing yellow pupils. She dresses in a white sweater paired with red shorts and faded red sneakers, and a set of cuffs rings her wrists.

Combat is Long's whole appetite. She fixates on the scent and flavor of blood and seems to crave little else, summed up by her single recorded word of dialogue: blood. She also carries a submissive streak and is most often pictured with her wrists shackled.

During the International Assassins arc, Long helps Quanxi and the rest of the fiends mop up the dolls still standing outside a shopping mall before Kishibe captures her. Hauled inside, she finds Denji holding a blade to her. When Aldo tries to step in and Denji lets her go, she locks Denji in a chokehold; Aldo opens fire, but she shields herself by raising an arm and spits a gout of flame back at him. He dodges and shoots again, only to be blocked the same way. Once Quanxi handles Aldo, Power warns Long to back off and free Denji or watch Pingtsi die, and Beam soon flings Long aside so Denji can slip away.

Long is later banished to Hell alongside the other devil hunters caught up in the chaos, panicking with her companions before the Darkness Devil kills her. She resurfaces as one of Santa Claus's puppets, wheeled out to rattle Quanxi. By the Aging Devil arc her body and those of the other fiends sit in Public Safety custody, and it is said Quanxi was reportedly drawn into Special Division 7 by a pledge that she would recover her dead lovers' bodies. As a fiend Long cannot strike devil contracts and ranks below her old devil self, yet she still breathes fire freely and proves a capable close-quarters fighter.
