Einzig

Einzig is the call sign of the current administrator unit of Ex-Machina, therefore making him the Representative of the cybernetic race. Much like Riku, Einzig acts like a cold, emotionless figure to accept the self-sacrifices of his brethren. He buried his grief deep in his heart in order to stop the war but actually cared about his clusters and could even name individual units. It was revealed to Sora that due to reflecting Schwi's feelings toward Riku, Einzig developed an attraction to the Immanity king due to his striking resemblance to Riku. He frequently called Sora affectionate pet names and was even able to find his entire hentai collection.
