17 Assassin Anime Shows to Watch

Samurai Champloo masterfully blends the world of feudal-era swordsmen with hip-hop culture. It isn’t a typical assassin anime, but its story often drifts into the realm of professional killing, and its leads, Jin and Mugen, are skilled enough swordsmen to be considered assassins in their own right given how efficiently they dispatch enemies. It’s a unique spin on the genre, showing how deadly martial arts can be in the right hands. Expect action, adventure, a dash of comedy, and unforgettable showdowns.

Basilisk transports viewers into a world of feuding ninja clans in feudal Japan, with a story that’s an intricate mesh of romance, war, politics, and betrayal.

As you move through its lethal world, expect to be thrilled, horrified, and moved by the tragic love story in equal measure.

With thrilling action, dark humor, and complex characters, it’s a reminder that female assassins can be every bit as deadly as their male counterparts.

Gunslinger Girl follows Henrietta, one of several young girls given cybernetic enhancements and conditioned by a covert government agency to carry out assassinations, each paired with an adult handler who directs her missions. It’s a deliberately bleak, unsettling series that uses this premise to ask hard questions about innocence, free will, and the moral cost of turning children into weapons. The discomfort is the point: the show never lets you forget what’s been done to these girls.

On a fateful night, twin siblings Suou and Shion are stargazing with their father when a falling star strikes them, turning Shion into a Contractor, a human granted powers at the cost of their humanity. Two years later, their ordinary life shatters when mysterious men raid their home; in the chaos, Shion vanishes and Suou ends up with the enigmatic Contractor known as Hei.

The twist comes when Tokaku finds herself drawn to protect Haru instead, turning the hunt on its head.

Hope’s Peak Private Academy promises top students a world-class education, but Makoto Naegi, an ordinary kid who got in by lottery, finds it’s anything but normal. He and 14 others are trapped inside, told that the only way to “graduate” is to murder a classmate and avoid being caught in a life-or-death trial. Overseen by the cruel, teddy-bear-like Monokuma, Naegi and the others must navigate this twisted killing game to survive and escape.

Code:Breaker is a great pick for assassination fans, blending action, supernatural powers, and moral complexity. It follows high-schooler Sakura Sakurakouji, who witnesses a boy, Rei Ogami, incinerating people with a blue flame. Ogami turns out to be a Code:Breaker, one of a group of powered assassins who eliminate dangerous people beyond the law’s reach. Each lives by their own reading of the motto “an eye for an eye, evil for evil,” and the series explores that murky world through Sakura’s eyes as she tries to understand the “necessary evil” they represent.

Black Cat weaves action, comedy, and adventure around Train Heartnet, once a ruthless assassin code-named “Black Cat” for the secret organization Chronos. His life changes course after he meets the bounty hunter Saya Minatsuki, who teaches him the value of human life. From elite killer to bounty hunter, Train’s journey is full of exciting battles, sharp twists, and memorable companions, including his former Chronos partner Creed Diskenth. It captures the duality of his character beautifully: the lethal assassin versus the man chasing redemption.

No list of anime with assassins is complete without Ghost in the Shell. Set in a cyberpunk future, it follows Major Motoko Kusanagi, a cyborg operative in Public Security Section 9 who handles high-level cyber-crime and assassination missions.

It’s a cold, ruthless, often grim window into the assassin’s world.

Phantom: Requiem for the Phantom is a haunting tale of two people stripped of their identities and forced into the world of professional assassination. Their journey blends suspense, drama, and action, and the show is at its strongest in the psychology of its characters, their struggle to reclaim their lost pasts, and their descent through an underworld ruled by fear and violence. It’s a tragic but riveting story about survival, identity, and the weight carried by those who live in the shadows.

Best friends Brandon Heat and Harry MacDowel survive by the law of the streets until a run-in with the wrong crowd costs them their freedom. With no allies and no way out, they join Millennion, the city’s dominant syndicate, and walk a path riddled with heartache, tragedy, and betrayal. Brandon takes up the gun to protect those he loves and to help Harry climb Millennion’s ranks, even when success means staining his hands with the blood of countless others.

Its inventive concept gives a fresh, funny spin on the assassin genre without skimping on action, and it’s a must-watch for anyone wanting something unconventional.

It’s impossible to talk assassin anime without Akame ga Kill!, which dives deep into a world of brutal, relentless killers where morality, power, and survival collide.

The series excels at walking the thin line between good and evil, repeatedly forcing you to question your own sense of right and wrong.
