Pluto

Pluto is a main character in Relayer. An AI who's psyche was copies from the brain of a young boy, Pluto serves as the Administrator aboard the Asterism. Intially just an AI helping run the ship, Pluto eventually was able to create his own personality and soul, allowing him to awaken as the Starchild of Pluto, making him the first AI Starchild in existence.
Pluto runs everything that Captain Gillian and Media doesn't run, which includes the ship's controls, steering, sensors and electronic warfare, making him the Asterism's battery and brains as Pluto puts it. This effectively allows the main deck to only be managed by three members, including Pluto himself. 
Pluto also controls the Netherworld, the Asterism's maiin computer which in turn controls the ship's navigation, it's offensive and defensive capabilities and maintain data links between the Steller Gears.
His Personal Steller Gear is Tenmu Asuka, a Sniper Type Gear that originally belonged to Himiko before she switched to The Original One. Pluto and Venus upgraded Tenmu into Tenmu Asuka and as a result, he can remote control it from the Asterism, similar to a drone piloting a Quasar.

Physically, Pluto resembles a young boy with shoulder lengh white hair and white eyes.
Despite being an AI, Pluto replicates the Male Asterism Uniform, with the tie and inside of the jacket being violet.
