Silence of Cause and Effect

Mu Guang is an ordinary high school student. On his seventeenth birthday, a dark figure came from the alley. The blonde girl Zero rescued him and handed him a contract - to join the star world and fight against an unknown existence called "Obstacle". The calendar always stops at the end of the year, everyone lives in peace, and only he knows something is wrong. The four gods stood silently behind him, knowing everything, but they were bound by cause and effect and could not speak a word. This road comes to an end and no one remembers it.
