Mitsuba

Piyon is a Hunter and is also is a member of the Zodiac Twelve with the codename "Rabbit."

Mitsuba is a female servant of the Zoldyck family. She became the first person other than Killua witnessing Alluka when he was in wish-granting mode after unintentionally fulfilling three consecutive requests made by him.

Kikyo Zoldyck then ordered Mitsuba to decline any request of Alluka to test his ability. Obeying the order, she declined Alluka's requests four times in a row and as a result was crushed into minced meat together with her lover Hasama, a butler of the Zoldyck family, by Alluka's power.
