The Mysterious Origami Master: Rising to Power from the Underworld!

(The protagonist is calm and self-focused, and refuses to be swept along by outside forces. Please understand if that's not to your taste.) After a family upheaval, he awakens as a bizarre paper-folding craftsman. After a paper mansion is burned down, it transforms into a haunted apartment building in the underworld. One paper figure after another becomes a battle-hardened general! With a wave of paper, he summons a river of stars across the heavens. With a drop of paper, the Yellow Springs surge into a dark forbidden zone. Paper scattered to raise an army, paper figures possessed by monsters, paper figures hauling cargo, taking another's place in death and changing form, turning paper into all things, offerings made real, paper souls crossing worlds, the city of wrongful deaths, a paper world that ferries souls across the mortal realm... The age of spiritual tides returns. The underworld is boundless, secret realms and grotto heavens emerge in the human world, and the myriad realms connect in subtle ways. This is an age of great strife! The underworld, the spirit realm, the human world... This is the story of an indescribable being from the myriad heavens as it grows!
