Zodiacs

The Zodiac Twelve (十二支ん Jūnishin) are a group of twelve hunters that have been recognized by Chairman Netero. The chairman would entrust them with the Hunters Association in times of emergency, and would also spar with them in his free time. They each have a codename associated with one of the zodiac signs, which most of them chose to match in appearance out of adoration for Netero.
