Firmament is a new type of subscription-based online game. Players are not charged by their equipment, nor by the duration they played the game. Rather, they are charged by the ‘Modes’ in which they play in.
From the Monster Mode, Guard Mode, Mercenary Mode, Adventurer Mode, Hero Mode, or the Boss Mode… As long as you wish, you can play as any one type of character in this game.
Decide your destinies for yourselves – whether it is to become the greatest villain, or the most courageous hero in this world.

Xiao Yu, who works as a professional gamer, has come by this game and learned how this can be his path to riches and fame.
Watch how he rises to become the final Boss from an insignificant Wild Monster, through the various ordeals and dangers lying in wait for him…
