The main character, Alpha, is a robot that seems just as human as everyone else. Most of the time, this fact isn't even relevant to the story. Most of the stories are short, and simple. Anyone looking for a deep, involved plot will be disappointed. In fact, I think it's its charming simplicity that I enjoy most.
While perusing some documentation, I became curious about the hostnames used in the examples given. I traced them back to Yokohama Kaidashi Kikou, an endearing but little-known manga. The setting is post-apocalyptic, at a time where the remaining population is already mostly adjusted to the environmental changes. You'd think it would be a depressing story, but it's actually quite uplifting. It's at times bizarre, but at the same time wonderful.
