One Piece: Rayleigh Adopted Me at the Start!

(One Piece, Points, Power Fantasy, Martial Arts, Heroine Undecided!) (Momonosuke dies in Chapter 307)

One day, a pillar of light descended not far from the Roger Pirates. At the pillar's location, Rayleigh discovered a child and adopted him, naming him Mislanda!

Many years later, Mislanda, who possessed a system, opened an era of his own. The Seven Warlords of the Sea, the Three Admirals, the Four Emperors, the Five Elders? Sorry, Mislanda said, you're all just tools for me to farm points!

Years later, Mislanda established his own vast faction and became the most terrifying existence in the New World!

Blackbeard: "Why is the Dark-Dark Fruit with you? Then what is this in my hand? It's so much weaker than yours!"

Kaido: "Holy crap! What did this guy eat? Why is his body so monstrously powerful?!"

Shanks: "We were friends when we were kids. Can't you stop holding a grudge against me? Go find someone else!"

The Marines: "Don't come any closer!"

The Five Elders: "We can't afford to provoke him! Hurry and summon Lord Imu!"
