Muichiro had run into Kokushibo when finish mission in a random forest. Kokushibo saw him, told him that he was his descendant, offered him to become a demon but Muichiro said no (obviously) and they started fighting. Muichiro is bloody and has some injuries (no lost limbs) and that’s were the story starts. you are either Muichiro or Kokushibo so take your pick.
