One Piece: I Become a Fallen Angel Starting with the Straw Hat Pirates

(Travels with the crew, no heroine, Fallen Angel Fruit, has family, grows without becoming invincible) After a career crisis, a young man was sent to another world by the mighty Truck-kun, who had gotten lost. That world was none other than the Pirate King world. He transmigrated into the Pirate King world as a little boy. He thought he would become the protagonist, but instead became a slave to the Celestial Dragons. He later managed to escape to an island and survive, but even after getting away, his body, broken in by the Celestial Dragons’ slave training, still left him plagued by frequent nightmares every day. He thought he would live an ordinary, uneventful life like this, separated from his younger brother in this world. But one day, someone found him… “Hey! You’re really interesting! Want to come aboard and become my crewmate?”
