In order to be an official, he served the merchant at first, but because of his excellent skills, the merchant became suspicious and wanted to kill him. Kato saw through Kenshin's plot and escaped in time. Takeda Shingen, the tiger of Jia Fei, was appointed as the military adviser.

One day, Takeda Shingen watched his performance with other ministers, which made him jump over a 3-foot fence and secretly put thorns under the wall, hoping to see his jokes. Unexpectedly, he noticed something strange in the air after jumping over the wall, but he jumped back to the wall.

This is an eye-opener for everyone. However, when Yasuke Yamamoto asked Takeda Shingen whether to hire Kato Duanzang, Takeda Shingen's answer was "cut off contacts". So Kato was given a banquet. Kato, who was absorbed in his career, got carried away, thinking that Takeda Shingen would accept him, and could not help but take it lightly. When he was drunk, the man with a knife lying in wait outside the door rushed in and killed him. A talented ninja died like this.
