D.Gray-man

Katsura Hoshino's D.Gray-man follows Allen Walker, a young exorcist wielding a cursed left eye and a sentient, anti-Akuma weapon known as Innocence. Published by Tokyopop from 2006, this dark fantasy series pits the Black Order against the Millennium Earl and his monstrous Akuma in a desperate battle to save humanity. With its intricate gothic aesthetic, tragic character arcs, and Hoshino's evolving, detailed art, it became a defining shonen manga of the 2000s for its blend of horror and heartfelt adventure.
