"If they're copying us, they must look just like—wait, they don't look like us at all!!"
About
I went to see who was copying us, and... huh?? 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, they send an advance notice to the owner to engage in a fair showdown. 3. They require quick judgment, precise calculation, the ability to think fast to avoid danger in traps and crises, and genius intelligence to turn a crisis into an opportunity. 4. Since life is not eternal, they value life above any treasure. They consider life more important than the loot.
