Free The Soul
Free the Soul, also known as Free the Soul of Y, is a cult that was searching for the Dragon Balls to further a nefarious plot to "cleanse humanity." Not much is known about them, except that the leader of the movement is known as "Brother." It is rumored that Free The Soul is involved in human cloning (which explains the Myrmidons) and has higher ups in positions of power at major corporations (such as Cradle Pharmaceutical.)
Currently, they have suffered a stinging defeat at the hands of the allies of Ten-Aino House/Hotel, and are rethinking their current plans.
The Myrmidons
This group of people all share the same looks: a man in his late 20s with dirty blonde hair in braids and green eyes. They are all given the name "Left," and were born and bred to serve Brother and Free the Soul. Each member is skilled in combat and carries a cyanide capsule should a mission go awry.
Amanda Sharlan was kidnapped by the Myrmidons and held hostage in exchange for the retrieval of the sixth Dragon Ball from Siberia. When the mission ended with the Myrmidon escort being killed by Suu and her party, Suu decided to rescue Amanda by herself and ended up as a hostage as well. During the battle between the house allies and the Myrmidons, the current generation of Myrmidons were all killed, setting back Free the Soul's covert operations by months.
