In an "accident," the protagonist loses his life, only to end up by a twist of fate in the Underworld, known as the "Second Hell." Under the Lord of the Underworld's coercion, he enters the world of Pirate King, equipped with the abilities from Katekyo Hitman Reborn!, including weapon Boxes and Dying Will Rings. He becomes one of the rising stars of the Pirate King world. On a small island in the East Blue, he meets another companion sent to the Pirate King world by the Lord of the Underworld: Han Xue. She also possesses the three Dying Will abilities from Katekyo Hitman Reborn!: Sky, Mist, and Rain. The two meet Luffy aboard a ship. With Luffy's help, they defeat the Abiata Pirates, who attack the ship, and establish the Straw Hat Pirates under Luffy's leadership. Zoro, Nami, Usopp, Sanji, Chopper, Robin, Franky, and Brook also join the Straw Hat Pirates, making them a force the World Government can no longer afford to underestimate.
This is my first submission. I hope you'll point out any shortcomings...
This novel and its characters are entirely fictional. Any resemblance to actual people or events is purely coincidental. Do not imitate.
I don't think tutoring skills are very powerful. In Pirates, you just play support. Even Gang's ultimate move can only penetrate a few walls.
