Summary
Joker makes his debut during the Circus Arc in Kuroshitsuji, serving as a member of the Noah’s Ark Circus, a troupe suspected of involvement in a string of missing children cases. Initially presenting himself as the Ringleader, his actual role is more akin to that of a hired manager, though most of the performers continue to address him as the boss since he oversees the main performances. He also possesses a prosthetic hand, which replaced the one he lost under mysterious circumstances during his youth and was crafted by the circus doctor.
