Anti-ESP Unit, alternatively Espers Subdual Enforcement Troop, is a special unit led by Torada. They were established due to increase of espers crime.
The organization suddenly formed after criminal espers attacked Rinka's school. They were tasked to capture espers and bring them to the Esper Reception Facility. They were also involved in attempts to fight the Professor. They first appeared in the hospital and managed to capture Rindo Urushiba and Roshi Yodani, while Rinka Urushiba and Murasaki Edoyama escaped. They appeared again invading Cayce's residence to capture Kobushi Kuroi, but she was able to escape as well. Rinka was later letting herself to be captured. They later invaded the Professor's hideout, but ultimately failed, due to the Professor's illusions.
