Is X/1999 Worth Reading?
Quick Answer
Yes, if you want one of CLAMP's most visually stunning and thematically ambitious works and can accept going in that it never received an official ending.
Quick Verdict
“Gorgeous, genuinely unsettling apocalyptic epic with one of CLAMP's richest casts, undercut by the fact it stopped mid-story in 2003 and was never finished.”
Best for: Readers drawn to CLAMP's art and ensemble-cast tragedies who can accept a story that stops rather than concludes.
Not for: Readers who need a complete, resolved ending, since X was never finished and both anime adaptations invent their own separate conclusions.

Overview
In CLAMP's X, the year 1999 is supposed to bring the end of the world, and Kamui Shiro is the psychic teenager both sides of that coming apocalypse need on their side. The Dragons of Heaven want to protect Tokyo's spiritual barriers and save humanity; the Dragons of Earth want those barriers destroyed so the planet can heal itself by wiping humanity out. Kamui's return to Tokyo after six years away, and his childhood friend Fuma Monou's transformation into the Dragons of Earth's own chosen "Kamui," sets the two of them on opposite sides of a war neither fully chose.
It's CLAMP at their most ambitious and darkest, an ensemble tragedy dressed in gorgeous, doom-laden art.
What it does well
The art alone makes X worth engaging with -- intricate character designs, striking dream sequences, and action scenes that still read as some of CLAMP's best work decades later. The real strength, though, is the ensemble: nearly every Dragon of Heaven and Dragon of Earth gets a real backstory and a real reason for the side they've chosen, which turns what could have been a simple good-versus-evil war into something closer to a tragedy with no clean villains. Kamui and Fuma's relationship is the emotional core, and watching childhood closeness curdle into opposing sides of an apocalypse gives the story real weight. X also commits to its stakes in a way a lot of similar epics don't -- named, developed characters die, and the story never signals that things will simply work out.
Where it falls short
The unavoidable issue is that X was never finished. CLAMP stopped serialization in 2003 after disagreements with their publisher over the planned ending, and more than two decades later it remains incomplete, with CLAMP only occasionally expressing interest in returning to it. That's a real cost for anyone going in expecting a resolution. Kamui's characterization is also inconsistent early on, shifting from a caring child to a noticeably colder teenager without much connective development. The tone grows considerably darker and more violent as the series goes, and that shift can feel abrupt set against its lighter opening chapters. And with a cast this large, a handful of Dragons get comparatively little development, leaving some arcs feeling thinner than the story's strongest threads.
Verdict
X is one of CLAMP's most visually accomplished and emotionally ambitious works, and its ensemble of doomed, fully realized characters is genuinely memorable. The catch is real, though: this is a story that stops rather than ends, and readers who need closure should know that going in. For everyone else, it's a striking, unsettling epic worth reading on its own terms.
Strengths & Weaknesses
Strengths
- CLAMP's art is at its most striking here -- intricate character designs, haunting dream sequences, and action choreography that still holds up decades later.
- The ensemble cast of Dragons of Heaven and Dragons of Earth gives nearly every major character a distinct, often genuinely tragic backstory rather than treating them as disposable combatants.
- Kamui and Fuma's relationship, from childhood closeness to opposing sides of an apocalypse, is one of CLAMP's most effective central dynamics.
- The story doesn't flinch from its own stakes -- named characters die, the world's fate stays genuinely uncertain, and the tone earns its apocalyptic premise instead of just gesturing at it.
Weaknesses
- The manga was never finished. Serialization stopped in 2003 after CLAMP and their publisher couldn't agree on how to print the planned ending, and it remains incomplete with no official resolution.
- Kamui's early characterization is inconsistent -- a caring child who reappears as a noticeably colder teenager without much bridging development.
- The violence and tone grow considerably darker as the series progresses, and the shift can feel abrupt against the series' earlier, lighter chapters.
- With such a large cast, some Dragons get far less development than others, leaving a few arcs feeling undercooked next to the series' stronger threads.
