The chief of all sorcerers in Cephiro and formerly Princess Emeraude's attendant, Guru Clef acted as a guide for Shidou Hikaru, Ryuuzaki Umi, and Hououji Fuu into becoming the Legendary Magic Knights. After Princess Emeraude died, he and all the other magicians of Cephiro used their willpower to create a castle to hold all the inhabitants of Cephiro. He became the leader of his people temporarily until a new Pillar could be found. Although thoughtful and mysterious, Guru Clef is kind-hearted, good-natured, and selfless.
Amazing cosplay by Issa! I never thought anyone could cosplay Guru Clef so well! Thanks again to Fumiki for sending this!
