Why it matters
It translates Katsura Hoshino's manga into television, giving anime viewers exorcists, Akuma, gothic institutions and machine-body horror with steampunk-adjacent visual force.
The D.Gray-man anime gives Victorian gothic adventure a machine-monster problem, which is exactly the kind of occupational hazard one expects when exorcists start sharing space with engineering.
Directed by Osamu Nabeshima and produced by TMS Entertainment, the anime adapts the manga's story of Allen Walker and the Black Order, an organisation fighting Akuma created by the Millennium Earl. The series mixes religious imagery, gothic fashion, body horror, tragic monsters and a late nineteenth-century mood that rarely looks in danger of cheering up.
The steampunk adjacency comes from design rather than engineering logic. Akuma are not steam machines in a tidy industrial sense, but they are mechanical demons, artificial bodies and weaponised souls. That places them close to the dark machine imagination: technology as corpse, prison, disguise and battlefield.
The Black Order gives the story its institutional shape. Uniforms, laboratories, missions and secret knowledge make the world feel organised in the way gaslamp and gothic fantasy often enjoy. It is an organisation built to fight evil, and therefore naturally develops corridors, rules and unsettling habits. These things happen.
Compared with the manga, the anime makes the atmosphere more immediately visible. Costumes, weapons and Akuma designs gain motion and sound, while the episodic structure lets the viewer linger in the mix of mission, tragedy and gothic spectacle. The adaptation helped many international viewers encounter D.Gray-man as a dark cousin to more overt machine-age anime.
Its relationship to Fullmetal Alchemist remains useful. Both works are concerned with bodies altered by power, institutional violence and young protagonists carrying adult damage. Fullmetal Alchemist uses alchemy and military science; D.Gray-man uses exorcism, gothic machinery and religious war. Neither is core steampunk, but both sit in the wider industrial-fantasy borderlands.
The anime's appeal is for viewers who like their retro-mechanical imagery with candlelight, uniforms and sorrow. It is less interested in invention as progress than in machinery as corruption or curse. That makes it a darker neighbour to the field, and a useful reminder that not every machine in this territory wants to help.
The visual palette matters. Black coats, religious insignia, ornate weapons and crumbling European spaces give the series a gothic pressure that sits comfortably beside gaslamp horror. When Akuma appear, their mechanical nature makes the horror feel manufactured rather than simply supernatural. Someone has built these tragedies, and that fact gives the monsters their sting.
It also broadens the anime side of the map. Not every relevant title is full of cheerful engineers, heroic airships or bright brass. D.Gray-man brings in grief, institutional secrecy and the idea that machines can carry souls badly. That is a grim contribution, but a memorable one.
The adaptation's length gives that atmosphere room to settle. The repeated missions, allies and losses turn the Black Order from a simple headquarters into a whole working system. That matters for the steampunk borderlands because institutions are often as important as inventions. A single machine can be frightening, but an organisation that keeps making machines for sacred war is worse.
Allen himself keeps the story from becoming only a parade of grim uniforms. His cursed eye, weaponised arm and stubborn empathy make the body a site of conflict. In a gentler story, machinery might simply empower the hero. Here it marks him, hurts him and makes him responsible.
Is it really steampunk?
No. The D.Gray-man anime is gothic shonen fantasy with steampunk-adjacent design. Its relevance comes from Akuma machines, Victorian styling, secret institutions, altered bodies and dark retro-mechanical atmosphere.
It belongs near gaslamp horror and anime machine fantasy, where the machinery has teeth, guilt and very poor bedside manners.
