Song of Light and Darkness

This is a legend about five organizations: the Heavenly Guard, the Assassin, the Cavalry, the Shadow, and the Alien. They are mutually reinforcing each other, and the struggle is never-ending. This is an epic centered on personal growth: obedience, doubt, preparation, self-improvement, and finally emerging as a leader. This is a journey full of three emotions: family, love, and friendship. They help each other and overcome all the hardships together.
