Yuuga Mitsugi is a member of the Five Wings Syndicate and a veteran of the New World Creation Plan, where he was given the 21-Form Enhanced, an improved two-eyed version of Sumire Muroto's, 21-Form Varanium Artificial Eye. Born blind, Yuuga was mercilessly bullied in his school until Professor Grünewald saved him using his second-generation mechanized-soldier plan.
