Otoyama, Kouta

音山光太

Kouta is a mysterious figure. He and Shipon share a romantic relationship, yet much about him remains unknown. He has an older sister who operates an astronomical observatory in Japan. He frequently offers advice that is just as enigmatic as he is.
He consistently earns a rank of C in every class, without exception, regardless of the subject's difficulty. When warned that Ayaka might attack Shipon during training, he demonstrates extraordinary piloting skills that exceed what his ship should be capable of handling. In another instance, during a simulator game where Rinna achieved Rank A and Shima achieved Rank B, Kouta scored Rank S. When Shima asks why Kouta does not perform to the best of his ability in class, given that he is capable of doing so, he simply replies that he wonders why as well. Pierre once remarked, "Talented hawks hide their talons," when referring to Kouta's skills.
