Hishita is a male butler serving the Zoldyck Family.
He first appears when Gon, Kurapika, and Leorio arrive at Kukuroo Mountain to free Killua from his family's control. Along with other butlers, Hishita meets them at the butlers' mansion and engages in a guessing game with the uninvited guests, where Canary's life is at risk.
Later, Killua contacts Canary to have her instruct Hishita to send cars to three specified locations, including one near the hospital where Gon is recovering. Hishita waits for Killua and Alluka at the designated spot and is instructed to drive them 60 kilometers to the hospital. When confronted by Illumi's Needle Humans, Killua orders Hishita to get them out of there.
However, Hishita refuses to comply with Killua's order unless Master Illumi commands it, revealing that he is also under Illumi's control.
