A humanoid machine was created that had no idea of human emotions. It was supposed to be used again and again to do evil things, but due to accidents, it was saved by a mysterious figure. After being reborn, it was separated from the person who saved it and was gradually refined and eroded by human emotions. After that, its heart was subverted again and again, and the final path it took seems to be unpredictable.
Intention: to feel the value of life from many interesting things in life, and to think about the insurmountable gap between ideal and reality, how to cross it, how to ignore it, how to get up from the abyss under the gap.
