パンドラハーツ [Pandora Hātsu] [Pandora Hearts]

A dark fantasy mystery serialized by Square Enix from 2006 to 2015, Pandora Hearts follows a young nobleman whose life is upended when a mysterious, forbidden ritual sends him to a nightmarish dimension known as the Abyss. There, he forms a contract with a powerful chain—a monstrous being—and returns to a world where nothing is as it seems. Created by Jun Mochizuki, this 24-volume series is celebrated for its intricate, labyrinthine plot, gothic aesthetic, and deep emotional resonance, weaving together themes of fate, sacrifice, and the blurred line between human and monster. It stands as a landmark work of mid-2000s manga, influencing later dark fantasy series with its twist-heavy storytelling and hauntingly beautiful art.
