Mizuno Tetsu was a time traveler and a Konoha chunin, but he was miserable and his strength was poor.
During World War II, he was short of people and became a chuunin.
In order to survive, he would not hesitate to serve Matt Dai tea and water every day, just hoping that Dad Kai would take a look at him when he opened the eighth door in the future.
As a result, the broken compass he picked up with him lit up.
The next second, he fell into the pirates and returned to the village three years later. Konoha time did not move for a second.
