One Piece: Transmigrated as Akainu, I Join the Straw Hat Pirates from the Start

After transmigrating into the body of Admiral Akainu, who would one day become Fleet Admiral, this iron-blooded soldier was originally destined to follow the same path. But halfway through, he awakened the Strongest Pirate King Mentor System. “I, Akainu, have always been upright and honorable, with an unyielding spirit. I will absolutely never become a pirate. Don’t even think about it.” “Join the Straw Hat Pirates and receive top-tier Conqueror's Haki!” “Join the Straw Hat Pirates and receive the Rinnegan!” “Join the Straw Hat Pirates and receive the Dark Human-Human Fruit, Model: Nika.” Looking at the increasingly generous rewards, Akainu couldn’t help swallowing. Maybe becoming a pirate wasn’t such a bad idea after all.
