Another Dorssian agent. He is highly respectful of his boss Cain. His name means X1 in German. X-eins has proven to be a skilled tactician, able to find weaknesses in an enemy after only observing it in battle once developing countermeasures for future battles. His respect and loyalty for Cain was shattered when he found out who and what he is. After listening to H-neun's recording from his special earring, he also found out that it was Cain who killed H-nuen because he was getting close. Eventually, he died in Cain's hands after he failed to avenge H-neun's death.
