One Piece: Begging Thatch for the Dark-Dark Fruit at the Start

(New book is out! Also related to Whitebeard! Slow-burn, no system!)(Blackbeard + One Piece + Whitebeard Faction + Loyal and Righteous + Not a Saint + Single/No Female Lead) If you treat me like a brother, I will defy the heavens to protect your smile! If you view me as your own, I will swear to protect our home with my life! If you choose to follow me, I will protect you with my life and never forsake you! If you like my book, I will diligently write chapters and never stop updating! The story is interesting, the synopsis is weak, the author is a goofball, and the imagination is huge! A slight bit of cringe, three devil fruits, grand ambitions, and the author is going strong! Jiehahaha! I am Blackbeard!
