Traveling into the comic book world, Zhou Mu opened an inconspicuous shop. As a result, the guy with Ichigo's face came to ask for credit, "Boss, give me a knife." The person wearing Sasuke's skin also came to ask for credit, "Are these eyes enough to pay off the debt?" - When they found out that what they owed was not money, but life.
[Conflict Bomb] The Shinigami borrows the Zanpakutō, the Hokage borrows the Sharingan, and the Pirate borrows the Devil Fruit. Those who come are confident until they find that the name written on the credit book begins to burn.
[Ability hint] Zhou Mu's account book is called the "Cause and Effect Book". He owes his debts and pays his life back, which is the law of justice. The greater your ability, the more you owe.
[Cool preview] When various protagonists were attacked by their own cheats and knelt at the door of the store asking for payment, Zhou Mu only slowly turned the page - it's time to pay back your karma.
