The Kingdoms of Ruin has built a real following in Australia on Crunchyroll, and in the US on Crunchyroll among viewers who want their sci-fi to think as hard as it looks. The show says what it needs to say in a single season, no filler. Its 8/10 TMDB score, built from 91 ratings, reflects a title that consistently delivers. Kaito Ishikawa anchors it with a performance that grounds the bigger ideas in something human. There is no real reason to keep putting it off — it is right there on Crunchyroll.

Part of the current wave of titles people are actually watching, The Kingdoms of Ruin earns its spot. The world-building is meticulous, but it is the characters who carry The Kingdoms of Ruin through its more ambitious moments. Witches were once respected for the wisdom and magic they gifted to humans. But with the rise of the Gear Expansion era, the new science community deemed them as enemies who hindered the progress of society. Thus began the slaughter of all witches, including one who had mentored a human boy named Adonis. The human element stays intact thanks to Kaito Ishikawa and Azumi Waki, who anchor every scene. It first aired in 2023. The Kingdoms of Ruin resists the temptation to explain everything, trusting the audience to sit with ambiguity. It rarely drops the ball, and when it does, it recovers fast.

Sci-fi fans who want ideas alongside the spectacle will find The Kingdoms of Ruin genuinely rewarding. The tonal similarities to Daemons of the Shadow Realm are real, though The Kingdoms of Ruin carves out its own identity quickly. The complete run is available and best experienced without too much prior knowledge of where it goes. Kaito Ishikawa anchors it with a performance that makes the more abstract moments feel personal. If you have been burned by ambitious sci-fi before, this is the exception.
