The best assassin anime take very different routes into the same dangerous profession: some turn it into comedy, some build a story around a team of rebels, and others focus on the cost of being trained to kill. This ranking weighs three things: how central assassination is to the story, how distinctively each series uses the assassin archetype, and how approachable its tone is for the viewer. The order is an editorial judgment, not a measured consensus.
To keep the list focused, it includes series where assassination is central to the premise or a major character arc—not every anime that happens to feature a killer. That means Hunter x Hunter qualifies through Killua’s story, though it is not an assassin series overall.

10. Gunslinger Girl
Gunslinger Girl is the most somber entry here. Its young protagonists are turned into cybernetic assassins, and the drama centers on what remains of their identity and humanity after that transformation.
It is a strong choice for viewers who want a character-focused story rather than a breezy action showcase. The premise makes the assassin role inseparable from the girls’ lives, while its subdued approach sets it apart from the list’s comedy and fantasy entries.
#1 Best Overall
9. Phantom: Requiem for the Phantom
Reiji is forced by the criminal organization Inferno into the life of an assassin and paired with Ein. That coercion gives the series a psychological and crime-drama angle: its central tension is not simply whether a mission succeeds, but what happens to people shaped into weapons.
Choose this for a darker, more serious story about criminal control and the people caught inside it.
8. Noir
Mireille Bouquet and Kirika Yuumura work as assassins while investigating their shared past. The partnership and the mystery are the draw: the story follows two professionals whose work is bound up with questions about who they are and how they came together.
Noir suits viewers who prefer a slow-burn mystery and a two-person dynamic over a large cast or a comic take on the profession.
Rank #2
7. Spy x Family
Yor Forger leads a covert life as an assassin while performing an ordinary family role. The contrast gives the series room for humor and warmth alongside its action, rather than treating assassination as a purely grim occupation.
This is an accessible pick for viewers who want domestic comedy mixed with a character’s hidden professional life.
6. Hunter x Hunter
Killua’s upbringing in the Zoldyck assassin family gives Hunter x Hunter one of its most compelling character strands. His background shapes his choices and relationships, but assassination is not the premise of the whole series: its broader story is an adventure.
That distinction matters if you want an anime centered on contracts or assassin organizations. Pick this instead when you want a wide-ranging adventure with a major character whose assassin upbringing is central to his personal story.
Rank #3
5. Golgo 13
Duke Togo is a professional hitman, and the contracts he takes structure the series. That procedural, episodic shape makes Golgo 13 a distinct option beside stories driven by a family secret, a rebellion, or a group’s shared past.
It is the pick for viewers interested in the work itself and a recurring professional figure, rather than a single coming-of-age arc.
4. Darker than Black
Hei, known as the Black Reaper, is an electrically powered Contractor who carries out assassinations in a dystopian Tokyo. The series combines the assassin role with science-fiction atmosphere and mystery, making its world as much a part of the appeal as its missions.
Try it if you want a moody genre blend instead of straightforward crime drama or comedy.

Tatsumi joins Night Raid, an assassin group fighting a corrupt empire. The premise turns assassination into part of a larger political struggle, with fantasy combat and high stakes built into the team’s rebellion.
This is the strongest match here for viewers after an ensemble, a corrupt regime to fight, and a dramatic fantasy-action story.
2. Assassination Classroom
In Assassination Classroom, students are assigned to kill their alien teacher, whose threat to Earth exists alongside his role as their mentor. That unusual tension lets the series combine school comedy and action with an emotional relationship at its center.
It is an especially distinctive entry because the target is also the students’ teacher. Choose it if you want an assassin premise with humor and a strong school-story framework.

Best Value
1. Sakamoto Days
A legendary hitman has retired to run a shop and live as a family man, but old enemies pull his skills back into use. Sakamoto Days earns the top spot for the way it sets lethal action against an ordinary domestic life, turning the gap between Sakamoto’s past and present into both its comic engine and its central hook.
It is the best starting point on this list for readers who want action with a light touch and a clear contrast between an assassin’s former life and the home he is trying to protect.
