X

Fifteen-year-old Kamui Shirō returns to Tokyo after six years away, carrying powerful psychic abilities and a fragile sense of duty. He comes back to look after his childhood friends, including Fūma and Fūma's younger sister Kotori, but his presence reawakens conflicts that reach far beyond personal ties. As opposing forces converge on the city, Kamui is pulled into a struggle over human destiny, and the series tracks how his choices ripple outward, testing loyalty, belief, and the limits of sacrifice without revealing the outcome.

Released in 2001, the TV adaptation was directed by Yoshiaki Kawajiri and draws on the original manga by CLAMP, whose credited creators here are Nanase Okawa, Tsubaki Nekoi, and Satsuki Igarashi. The show features a notable cast of voice talent, including Junichi Suwabe, Kenichi Suzumura, Masaki Aizawa, Houko Kuwashima, and Toshiyuki Morikawa.

As a CLAMP property with a stark, apocalyptic mood, X helped reinforce the creators' reputation for dark, fate-driven storytelling. Its stark visual style, moral dilemmas, and intense character conflicts have kept it in fan conversations, and it shows up frequently when people discuss anime that mixes supernatural spectacle with intimate drama.

Critics and viewers tend to praise the series for its strong animation, atmospheric score, and voice performances, while some point to uneven pacing and an unrelentingly bleak tone as drawbacks. On one public rating it holds about a 7.34/10 from 105 votes. Recurring themes include destiny versus free will, the cost of protecting others, and how personal loyalties collide with larger ideological battles.

The show did not become a major awards contender on the international stage, but it remains a recognizable entry in early 2000s anime for fans of character-driven supernatural drama and for those who follow CLAMP adaptations.
