teranoid is an alias of Japanese BEMANI musician and producer Kosuke Saito, most widely known as kors k. Under this alias, he produces music in the nu-style gabba and UK Hardcore genres. He also often works with MC Natsack under this moniker to form the duo teranoid&MC Natsack. Kosuke often jokingly refers to teranoid as a female, and in the third person. Although teranoid and kors k are both psuedonyms of Kosuke Saito, they are treated as two separate entities. When gigadelic first appeared in beatmaniaIIDX 11 RED, there was much confusion as to the identity of teranoid.
