Unleash the Underworld: The Top Demon Anime You Need to Watch Now

So, let's just get this out there: if anime writers have one thing down to a science, it's how to make demons (or, honestly, anything with horns and a tragic backstory) impossible to look away from. Whether we're talking unstoppable monsters with chainsaws for heads or demon lords stuck manning the fry machine, supernatural nasties have clawed their way into some of the wildest and weirdest stories out there. For anyone looking for that sweet spot where bloody action collides with existential dread (and the occasional completely absurd joke), here's a look at the best TV anime built around demons, devils, and demon-adjacent types. There are old-school classics, newer hits, and a few personal favorites. Let's dig in.

Berserk (2016–2017)

Let's be real—Berserk is a legendary horror/fantasy epic, and every adaptation struggles to do justice to Kentaro Miura's original masterpiece. This run picks things up after the infamous Eclipse (aka the moment where you realize, nope, this is not a regular medieval fantasy). Guts and Casca are left shellshocked from truly horrific supernatural trauma, and now it's endless demon slaying as Guts carries his giant slab of iron around, hunting down members of the God Hand. The CG animation? Not great. The archdemons? Unforgettable. And the ongoing nightmare vibes are strong as ever, even if it's still not the full Berserk experience every fan wants.

Claymore (2007)

If you like your demon-hunting spiced with moral ambiguity, Claymore is the hidden gem you should actually watch. Set on a single island ruled by demonic Yoma (think, shapeshifting soul-eaters) and almost exclusively defended by half-human, half-demon women known as Claymores, the series explores the psychological toll of fighting monsters by becoming one. Clare, our main warrior, serves up sword fights and personal angst in almost equal measure, while the show balances brutal action with a surprisingly intimate look at friendships, rivalries, and trauma. The story is darker than most but never drags. Bonus: the animation still holds up.

Black Butler (2008–2014, 2024–)

For something completely different, there’s Black Butler, an anime that jams together supernatural action, horror, and actual comedy, then drops it in Victorian England. Ciel Phantomhive—at thirteen years old, because of course—loses his parents and makes a literal deal with the devil (well, a demon). Cue Sebastian, the ever-smirking butler/demon/occasional cat enthusiast, who exists to both protect and torment his young boss. The show’s tone is all over the map, but somehow the blend of horrific violence and deadpan humor just works. Sebastian and Ciel’s relationship veers between pitch-black and laugh-out-loud ridiculous, which is exactly why fans keep coming back.

Chrono Crusade (2003–2004)

Chrono Crusade takes the kind of oddball premise only anime can get away with and runs with it: 1920s New York, gun-toting nuns, and a demon sidekick whose powers drain his partner’s life. Sister Rosette is the definition of 'chaotic good,' while Chrono’s brooding, tragic-demon routine is the necessary contrast. The action is fast, the emotional beats actually land, and sure, it veers way off from the manga, but there’s so much heart here that it’s hard not to care. For fans of doomed partnerships and supernatural slapstick, this one’s criminally under-watched.

Inuyasha (2000–2004, 2009–2010)

The early 2000s would have looked very different without Inuyasha anchoring late-night TV blocks. Kagome lands herself centuries in the past—and immediately runs into a Shinto horror show of demons, curses, and, crucially, the half-demon Inuyasha (if you haven’t seen his hair, just Google it, you’ll understand the hype). Their quest for the shattered Shikon Jewel is like Pokémon, if Pokémon involved more beheading and snarky love triangles. Still iconic, still kinda goofy, and—credit where it’s due—still one of the best introductions to Japanese folklore and monster mythology. Don’t be surprised if you get sucked right in (pun intended).

Blue Exorcist (2011– )

Okay, so here’s a setup: Your dad is Satan. You and your twin inherit wildly different powers (one brooding and skilled, the other, uh, literally bursting into blue flames). Blue Exorcist combines Catholic demonology with Japanese monster spins—a weird but surprisingly seamless cocktail. Rin, the blue-flamed lead, juggles his anger, his destiny, and exorcism school, while his brother Yukio just deals with existential crises in between lectures. Expect biblical verses, Buddhist mantras, and one of the weirdest magical high school rosters in anime. The only real downside? The glacial wait between seasons.

The Devil is a Part-Timer! (2013, 2022–2023)

Sometimes demons just want a steady paycheck. The Devil is a Part-Timer! is what happens when the Big Bad of a fantasy realm gets teleported to Tokyo and is forced to grind for a living at McRonald's (yes, legally distinct from the real thing). Watching Lord Satan get obsessed with employee-of-the-month competitions and instant ramen somehow never gets old. Unlike the others on this list, it goes all-in on comedy, and the jokes about surviving in the capitalist hellscape of minimum-wage jobs hit maybe a little too close to home these days. Not for people looking for dark drama, but genuinely hilarious if you’re in the mood for demon-infused workplace misery.

D. Gray-Man (2006–2008)

If Victorian misery is your thing, D. Gray-Man is the beautifully tragic saga you need. Allen Walker joins the Black Order to fight Akuma—the closest thing this list has to pure demons, even though they're technically weaponized dead people in demon costumes, but let’s not split hairs. The show mixes great action and classic horror with just enough character drama to hurt. Monster designs? Top tier. The only real misstep: the sequel, Hallow, rushes through way too much story and, frankly, the English localization is a mess. Stick with the original run for the good stuff.

Yu Yu Hakusho (1992–1995)

Pretty much the gold standard for '90s supernatural shōnen, Yu Yu Hakusho starts with delinquent Yusuke dying to save a kid, then gets immediately weirder. Yusuke lands a new gig as a Spirit Detective, in charge of stopping supernatural crimes using his ability to finger-gun ghost energy at bad guys. Backed up by a squad of demons and reformed jerks (shout-out to Kuwabara, Kurama, and Hiei), this show has everything: tournaments, friendships, betrayals, and plot twists that actually surprise. The animation is a bit creaky by modern standards, but the cast and the sheer momentum make it essential viewing.

Castlevania (2017–2021)

Leave it to Netflix to finally crack the 'good video game adaptation' curse. Castlevania is bloody, atmospheric, and—against all odds—actually takes its source material seriously enough to have stakes (no pun intended). Trevor Belmont isn’t exactly a model hero—he’s half-drunk, all attitude—but when Dracula goes on an apocalypse rampage after his wife is killed, Trevor has to ally with a magic-user and Dracula’s own half-human son. The show’s fight sequences? Absolutely wild. The story gives its villains as much attention as its heroes, which is why the climactic Trevor vs Dracula showdown lands so hard. If you want brutal, medieval monster hunting with brains and blood, this is your show.
