Harmonia is a Japanese post-apocalyptic visual novel developed by Key, a brand of Visual Arts. It was released on September 23, 2016 for Windows on Steam, and was available in English before its Japanese release on December 29, 2016. It was later ported to the Nintendo Switch. The story is set in a world where artificially intelligent, emotional androids called Phiroids were developed before a rapid decline in human civilization. An emotionless young man named Rei with a mechanical right hand is cared for by a girl in a small town as he gradually learns how to express emotions.
