Einzig

Einithi is the callsign of the administrator unit of Ex-machina, therefore making him the Representive of the cybernetic race.

Appearance
Like all Ex-machina, Einithi reassmble an young and attractive Imanity male with red hair except for having machanical part spring out from his body. In the light novel, he had a scar that cut across his nose as courtesy of war. Despite being more than 6000 years old, comparable to non-aging Jibril, he looks only slighty older than Sora in the latter's view.

He initially wears a funeral dress-like black cloak when he first address himself to Riku Dola to bring an end to the ancient war. However, by the time of his re-appearance in Elchea Kingdom, he dressed himself in a same-coloured yet more casual butler outfits, only wear the cloak in traveling.

Personality
As the Ex-machina have a shared mental, the administstrator refer himself or themselves as worse than mindless machine. With "Einithi" is a callsign for him and his predecessor unit rather than an individual's given name. Being blunt and direct like a robot. Thinking himself only become warmer after Shuvi's last upload and thankful for the act.

Much like Riku, Einithi acts like a cold, emotionless figure to accept the self-sacrifices of their brethmen. Buried his mourn deep inside his heart in order to stop the war. As a matter of fact, he had named a considerable amounts of his brothers and sisters and capable to recite all of these names.

It was revealed to Sora that due to reflecting Shuvi's feeling toward Riku, the male ex-machina had become homosexual and attracted to the imanity king and it become personal despite having laid down Shuvi's shadow via Ten Pledges, much to the latter's horror.
