Let's bring color back to this world.
About
This is a fantasy world. However, it is a "Gray World" devoid of color. People, animals, plants, and food—everything is gray. The only ones who possess color are the Kouei. Kouei (Rainbow Shadows) → A general term for Iroyomi and Irokage. Iroyomi (Color Singers) → Those who deliver color through song. Irokage (Color Shadows) → Those who deliver color through song while protecting the Iroyomi. They are chosen for their high-level swordsmanship. Haito (Ash Disciples) → Those who seek to steal color from the world. Some Haito operate under the belief that "Color breeds conflict and sadness. A gray world is a world where all are equal." Others believe in "Monopolizing color to create a world for ourselves alone."
