Etzali  

Mitsuki Unabara, エツァリ

Etzali was an Aztec magician who belonged to Return of the Winged One, a magical organization. He was tasked with monitoring the growth of the Kamijou Faction in Academy City. Despite being initially successful in his mission, he was eventually defeated by Kamijou Touma and joined GROUP. Etzali usually appeared as Unabara Mitsuki but had a true form that resembled a young man with dark skin and black wavy hair. Before August 31st, he was sent to Academy City to assess the danger posed by the Kamijou Faction and its potential impact on the balance between magic and science. His mission began when he abducted Unabara Mitsuki and assumed her form a week before August 31st, with the objective of taking Mikoto's form and sowing distrust among Kamijou and his peers. Despite following orders, Etzali admitted to falling in love with Mikoto.
