The protagonist, who discovers the world he lives in is an illusion and must fight to save the real world and protect the people who still live within the illusory world. He is a talented pilot and serves as the Altair Zegapain's Gunner. Kyo is an enthusiastic person who gets good grades and loves to swim more than anything else, but can also be reckless and become easily frustrated when he finds he cannot understand what is happening around him. As the anime develops, he begins to develop feelings for Kaminagi and vows to protect her. He has no memories of his past life, which he only learns of from Shizuno.
According to Shizuno, his past self was thoughtful and prudent and kept his emotional pain to himself. His character had been changed by wet damage before he met Shizuno such that his original character is actually closer to Version 2.0.X. Lu-Shen respected (or idolized) him, May-Yu and May-Yen both seem to have crushes on him, and Minato has never met him. His past self seemed to have had a relationship with his co pilot Shizuno until he had lost his memory having obtained too much wet damage after he had self-destructed himself in the battle for the moon server. He left messages for his future self to prevent himself from making the same mistakes and exhausting himself emotionally from the strain of being a Celebrant.
