Garyuu

One of Lutecia's many insect summons. Unlike the others his size is closest to a human. Acting as a counterpart to Erio as Lutecia does to Caro, Garyuu is the most intelligent of Lutecia's summons and the only one capable of thinking independently in order to protect her even against her commands. Garyuu's elbows and forearms sheathe blade-like growths - when Lutecia went berserk, Garyuu further grew a pair of tendrils from his shoulders and a trio of metallic, blood-soaked blades from his forearms. This alternate mode also caused him to cry tears of blood - Caro remarked that Lutecia was hurting Garyuu by forcing him into this boosted form. He also possesses the ability to camouflage himself and is superior to Erio in aerial mobility. -Wikipedia-
