I Have Infinite Lives in the Straw Hats

Ronan, a construction worker who has never watched One Piece, accidentally traveled to the world of One Piece. He has a growth system that can infinitely superimpose health points. By chance, he became the "shield against enemies" of the Straw Hats. "You should rest first, Luffy, and let me buy you some time." "Don't worry, prepare your sword moves, Zoro. Leave your back to me." "I will protect you, Nami." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
