Ena, an androgynous Shikabane bound to the Shichisei, pursues beauty’s fleeting essence with obsessive fervor. Once a sculptor, he fixated on a young model whose accidental disfigurement shattered his ideal. Ena strangled the boy in rage, convinced true beauty crystallized only in the liminal space between life’s defiance and death’s inevitability. He enshrined the corpse in an elaborate ritual, laboring until his own death transformed him into a Shikabane eternally tethered to the boy’s remains.

Cursed with consciousness-transferring regeneration, Ena wields a spinning metal ball that pulverizes matter to dust. His artistry warped into violence, abducting and killing youths to replicate his morbid epiphany. Hazama of the Shichisei harnessed this destructive zeal, valuing Ena’s brutal craft above survival instincts.

Ena slaughtered the Hoshimura Clan, delivering Makina’s mortal wound. Later, he puppeteered Ouri’s body to kill Keisei. Makina retaliated by destroying his cursed metal ball during a confrontation, exposing his fractured history: Ena’s suicide stemmed from perceived artistic failure, followed by centuries of corpse-hopping to evade imperfection. His cycle of carnage ended when Makina severed his curse’s anchor, erasing him from existence.
