Hikishio No Toki - Volume 1

He's about the unlikeliest "hero" you could imagine - the Administrator. Sitting alone - very alone - at the head of a hierarchy of robots, he has a kind of absolute local authority - but one severely constrained by those same robots. He mediates between a bureaucratic off-world "Federation" with off-world military forces anxious to supplant its authority on the one hand, and on the other the conflicts between and conflicting rights of the sometimes primitive native inhabitants and off-world settlers. For he is not just an administrator, he's a colonial administrator, part of a system to administer worlds after a period of extensive war and conquest. (Volume 1 of 5; written in Japanese)
