Kuina

He is the leader of the Dragon Knight Squad and only member to remain on La'cryma. He had feelings for Kosagi, but his affections were not returned. Eventually, his body decayed to the point of using mechanical prosthetics and a face mask to cover his eye and later most of his head. Prior to the series, Kuina realized La'cryma was a lost cause and had decided to ally himself with Noein to enter Shangri'la. However, due to Haruka's power increasing and Kuina's own body disintergrating, Noien refused to fulfill his end of the bargain. Kuina's obsession with reaching prompts him to take Haruka there to force Noein to honor their deal. However, his body is rejected by the timspace and he disintegrates. Kuina has not shown any spin weapons, though one may assume that, as a Dragon Knight, he possesses at least one. Kuina is Japanese for rail.
