Satoru Gojo's Limitless Technique Explained: How It Works, Physics, and Hidden Weaknesses (Full Analysis)

Modern Japan hides three jujutsu schools, a conservative sorcerer aristocracy, and a Curses population that the state prefers to pretend does not exist. Every arc peels back a layer of that governance until Shibuya makes clear that the old order was rotting all along.

• Fearsome Womb — Yuji, Megumi, and Nobara take their first mission at the juvenile detention center.
• Vs. Mahito — The introduction of Junpei and the transformation of Yuji's shonen ideals into something colder.
• Hidden Inventory / Premature Death — Gojo's past — the arc that made a generation understand why he laughs so much.

The world is a single ocean broken by the Grand Line, a lawless sea that spirals through four seas and one Red Line. The World Government sits on Marie Geoise, the Marines police the seas, and the Revolutionary Army wages a slow war against the Celestial Dragons. Every island Luffy touches is its own genre — western, samurai, sky pirate, fish-man kingdom — and every one of them adds a piece to a single global plot.

• East Blue Saga — The founding of the Straw Hats. Every crew member gets a full origin, culminating in Arlong Park.
• Alabasta Saga — Baroque Works, Crocodile, and a desert war that sets the political scale of the world.
• Sky Island Saga — The most divisive arc becomes one of the most rewarded in retrospect: Enel, Skypiea, and the Bell of Shandora.

Paradis is an island prison for the descendants of a race the rest of the world blames for a genocide. Marley is a decaying industrial empire that recruits child soldiers from that same people to keep its Titan monopoly. Nearly every arc reframes who the enemy was, which is why the show rewards a rewatch more than almost any other modern anime.

• Trost — The fall of Wall Maria, Eren's first transformation, and the reveal that humanity has weapons it didn't know it had.
• Female Titan — Annie's arc turns the show into a thriller and burns the Survey Corps down to its bones.
• Uprising — Politics take the throne: the crown behind the crown, Historia's ascension, and the true face of Wall Rose.

The world is split across three planes — Living World, Soul Society, and Hueco Mundo — governed by parallel bureaucracies. The Gotei 13, the Central 46, and the Royal Guard sit above the visible plot for most of the series.

• Substitute Soul Reaper — Ichigo learns what he is, meets the Soul Society's rules, and picks up his first real fight.
• Soul Society — A rescue mission turns into a coup. The Gotei 13 is introduced properly, and Aizen's betrayal reframes the entire series.
• Arrancar / Hueco Mundo — The Espada arrive and the war moves into Aizen's territory.
