Master, your design is wonderful. The disadvantage is that it is too free. I am afraid that it will be too explicit and I will not be able to see the ending. I don't remember where I saw the second-hand props. All the props are equipped with devices to detect whether the user has committed a crime (the protagonist group in the original comic has a lot of crimes). Even children can use it. Only Doraemon's second-hand props will be dismantled for tax avoidance. It can be inferred that there are relatively few restrictions on props used by military and criminal groups.

The author has good writing style. There are very few fanfictions that are not brainless. At least this one is definitely not. Wonderful [Blow kiss]
