Knuckle's reading ability has a very interesting name, which is "I don't know what is unique". It can be seen from the name that this reading ability is quite interesting. His reading ability can lend his reading ability to the enemy as wealth. And the loan interest is still high, just like usury in life. Once this reading ability is started, you can lend money to the other party without the consent of the other party. It can be seen that this reading ability is still very overbearing. His reading ability is not very aggressive, but he relies on wisdom to outsmart his opponents.
The fat doll that appears behind the enemy after the knuckles use the mind-reading ability is the summoner used to calculate the loan amount. The ability of knuckles is actually to compare the reading ability of both sides. Once the other party borrows too much, it will have serious consequences, that is, it cannot be used again within 1 month.
Although Knuckle face value is not loved by the audience, his personality is the reason why many viewers love him.
