The Twelve Kingdoms

2002–2003 4 Seasons 45 Episodes Animation PG ⭐ 8 / 10

The Twelve Kingdoms has built a real following in the US on Crunchyroll and The CW among viewers who want their sci-fi to think as hard as it looks. 4 seasons in, and the quality has not slipped. An 8/10 rating says what the writing already makes obvious: this one works. Takehito Koyasu's performance is the anchor the more ambitious scenes need. Available now on Crunchyroll — press play and find out why people keep recommending it.

Part of the current wave of titles people are actually watching, The Twelve Kingdoms earns its spot. The world-building is meticulous, but it is the characters who carry The Twelve Kingdoms through its more ambitious moments. Nakajima Youko is your average somewhat timid high school student. One day, a strange man named Keiki appears before her, swearing allegiance. Before she could properly register what was happening, demon-like creatures attack Youko and her friends, after which they are pulled into a different world. Takehito Koyasu and Kenichi Suzumura lead a cast that keeps the bigger ideas grounded in something human. Across 4 seasons (2002–2003), it never lost the thread that made it worth starting. The rules of The Twelve Kingdoms's world are consistent enough that the big swings never feel like cheating. The hit rate here is high enough that skipping ahead never feels like an option.

The Twelve Kingdoms is satisfying on multiple levels — something to watch and something to think about after. Fans of Loner Life in Another World will recognise the sensibility here immediately. Short enough to finish in a weekend, substantial enough to feel satisfying. Watch for Takehito Koyasu in particular — the performance elevates the material. Satisfying on multiple levels.

The Twelve Kingdoms wrapped up in 2003 — and 4 seasons are available to watch from start to finish.
