One Piece Simulator

A realistic, autonomously evolving Pokémon world, where you are just one of the many travelers.

An owl finds you in the summer of 1991 — same year as Harry Potter. Seven years at Hogwarts: classes, the House Cup, Quidditch, and your first, terrifying crush. The dark stuff is out there if you go looking.

Summer 2006. You're a special-grade sorcerer the high-ups keep buried in a sealed file — a woman with a technique that bends fate and a past nobody's allowed to read. The Hidden Inventory arc is just beginning.

Taishō-era Japan. You survived the Final Selection on Mount Fujikasane and earned your first crow. Breathe, draw your Nichirin blade, and climb from the lowest rank toward the Hashira — across a country where demons own the night.

Enroll in U.A. High, master your unique Quirk, and leap to the top of the Pro Hero rankings.

Marauders era, 1976. Laugh in the halls, duel in the dark, and find out who you’ll become when the war begins

AC 297. A new Hand rides south and the realm holds its breath. You're nobody the songs remember — a lowborn striver or a lesser-house cousin — living one month at a time as winter and war come for the Seven Kingdoms.

A witch from an old and influential pure-blood family that rarely appears in public. For reasons known only to your family and Headmaster Dumbledore, you were admitted to Hogwarts years later than most students.

Survive. Trust few. Fear everyone.
