Nio

Nio is a mysterious figure within the assassination organization known as 'Riben-ya,' possessing an almost angelic appearance paired with a genderless, captivating charm. Specializing in lethal missions, he wields kite strings embedded with glass shards as his primary weapon. Beneath his carefree, childlike demeanor lies a cold-blooded killer utterly devoid of moral conscience and indifferent to human life.
