Product Explanation ■ In every world, it is difficult to form true bonds, but once they have been formed, it is extremely strong and hard to solve.
The original plan was created with such an image, but this time as a cast puzzle, it has become a puzzle that is truly an unsolvable bond.
How do you break this bond and how do you tie it?
There are two types of kumikata, so I want you to try both.
