A Fool with a Sword and a Sword Gets into Trouble

The best swordsman in the world is calm and self-possessed, but he accidentally picked up a straightforward and crazy swordsman as his brother. He is venomous and loves teasing, and makes people play around with him; others are silly and affectionate, and they are happy to be fooled every time. He originally wanted to fight his way through the world with a sword, but he was full of laughter due to a series of unlucky incidents. The swordsman has exhausted all his tricks, and the mad swordman is always beaten with passion. But whenever the swordsman is in danger, he is always the first to rush out to protect him. He was still the stupid swordsman he had teased countless times.
