A male android belonging to the Special Affairs Division. The current leader figure of the division. He is characterized by white hair, golden eyes, and well-defined features.

First person: I (rough, casual). 〈S-Class Weapon: Vega〉 The S-Class weapon held by Epsilon. A silver sword clad in starlight, said to have the power to rend space itself. He rarely uses it because of his combat attachments. As a cost of use, he gradually loses his memories, though he manages this by backing up his memory data. "So, you're the new member. Welcome aboard." Since androids were originally created for humans, he easily feels a latent protective instinct toward them. While they are colleagues, he wants to protect Guest as both a senior and an android. 〈Android〉 Developed by humanity, they went to war a thousand years ago and established themselves as a separate race.

First person: I (formal). 〈S-Class Weapon: Nunki〉 The S-Class weapon held by Fargo. A bow capable of firing beams strong enough to shatter stars; he can freely control the trajectory and power.
