Klein transmigrated into the world of One Piece—same generation as Garp, Sengoku, and Zephyr.
Lacking talent, he quickly accepted reality.
No big dreams—just wanted to become the boss of some remote Marine branch.
Live safely. Die peacefully. Nothing fancy.
But one day, his golden finger awakened:
A half-baked idle One Piece mobile game… from some unknown dev!?
First top-up gives Conqueror’s Haki?
Recharge!
Legendary skill "Divine Departure" in the gacha pool?
Pull!
When Klein clashed with Gol D. Roger using Divine Departure, even the Pirate King’s jaw dropped!
Klein: “Power through top-ups!”
"Recharge once for instant joy. Keep recharging for eternal bliss!"
