Young Tsunayoshi came to the world of pirates.
It was picked up by Rayleigh who was wandering near the Shampoo Land at that time, and he kept it at Rayleigh's place. He saw many unfair things in the Shampoo Land. Although Reilly said this was the status quo, he could not ignore it. He could not agree with such a distorted world view.
One day, Tsuna's overbearing aura broke out when his fish-man friend whom he met by chance was abducted by pirates and almost sold to the Celestial Dragons as slaves.
Rayleigh stopped the incident from happening and began to teach Tsuna how to master the Haki of the Overlord Color and the Haki of the Armed Color and the Knowledge Color.
After Luffy fell into the water and disappeared in front of the Shampoo Land, Rayleigh and Xia Qi would always think of Tsuna after meeting Luffy, and they also mentioned it several times in front of the Luffy Pirates, making Luffy and the Pirates very curious about Tsuna.
Tsuna returned to his own world through water.
Mission: freedom, equality, justice
