One Piece: I Sign In with the Straw Hat Pirates

Jiang Ye transmigrates into the world of One Piece and awakens a sign-in System. As long as he signs in at a new location, he can claim a reward. “Ding! Signed in at Foosha Village. Received Yhwach Power Fusion Card.” “Ding! Signed in at Shells Town. Received the long swords Moonlight and Meteor.” “Ding! Signed in at Orange Town. Received a psychic sniper rifle with an infinite magazine.” Luffy: That guy Jiang Ye is seriously amazing. He always has incredible stuff to pull out! Zoro: The swords he gave me are pretty nice. Nami: Explain why my title is Elemental Witch! Jiang Ye: You don't like it? Weather Report, your Stand, can control the elements. Doesn't the title fit perfectly? (Momonosuke must die + making up for regrets + summoning characters from other worlds)
