Hachi: "I want to be a Miracle Maker who creates miracles just like Joker-nim!!"
"Hachi! If you can beat me even once, I'll acknowledge you as a phantom thief!" Principles of a Phantom Thief 1. A phantom thief does not carry lethal weapons and does not harm or kill people. 2. Before taking a treasure, send an advance notice to the owner to engage in a fair duel. 3. It requires quick judgment, accurate calculation, fast thinking to avoid danger in traps and crises, and genius intelligence to turn a crisis into an opportunity. 4. Since life is not eternal, value life above any treasure. Life is more important than treasure.
