Coppelion is an action-packed sci-fi anime with beautiful animation and a tight emphasis on friendship and hope. The main characters start off as other-worldly individuals but become more humanized as the series progresses.

Coppelion is also an emotional roller coaster that delivers excruciating emotional scenes involving its characters and the people they come across during their missions. Fans of powered-up main protagonists will enjoy the assassin-like shenanigans Coppelion’s cast finds themselves in.

This anime takes place in post-apocalyptic Tokyo. The reason for its destruction stems from a meltdown of a nuclear power planet. This led to Tokyo becoming a mere ghost town. However, when the Tokyo Self Defense Force receives a distress signal, they dispatch an all-female unit called Coppelion to scout the area for survivors. Unfortunately for the girls, they’ll be in for a dreadful time.

City Hunter

City Hunter is a classic action and comedy anime with a stellar protagonist, grand action scenes, and humorous dialogue. While the action and comedy lean toward realism, there are some nods to superpowers concerning its protagonist’s phenomenal skills.

Fans shouldn’t go into City Hunter expecting an overarching plot, though. While it does feature a few one-to-three episode mini-arcs, City Hunter feels more episodic in nature. That’s not to say the content present in its episodic content isn’t worth watching. The content itself will impress and please those who enjoy self-contained narratives.

Furthermore, its protagonist Ryo Saeba has a colorful personality. He’ll find himself in many dangerous circumstances and deliver a worthwhile beat down to criminals and adversaries. He also has a humorous persona whenever he’s near a woman. The other characters in the series are complex and well-developed too.

If you’re looking for an assassin anime with an episodic structure and memorable characters, check out City Hunter.

Kill Me Baby

If you’re looking for an assassin anime with more emphasis on comedy and slight action, Kill Me Baby has you covered. This thirteen-episode anime series is full of gag humor and school-like activity. While its storyline isn’t too memorable, the amusing dialogue and slapstick shenanigans make it a worthwhile experience.

The animation isn’t groundbreaking either. The art style works with the comforting and wholesome nature of the jokes present in the anime. The soundtrack and its characters are Kill Me Baby’s best achievements. The sound design works to capture the raw energy present in each scene.

The characters may appear annoying at the start, but they gradually transform into enjoyable protagonists. On one hand, you have an active assassin while on the other you have an air-headed and aloof personality. It’s twisted but somehow works within the context of the anime’s premise.

If you have the patience, I’d recommend giving Kill Me Baby a chance.

Assassination Classroom

Assassination Classroom

Assassination Classroom is an action comedy assassin anime about a group of delinquent school students needing to assassinate their homeroom teacher within a set time limit. Unfortunately, their homeroom teacher is an Octopus-like alien that can travel at fast speeds.

While this is a massive hurdle for them to hop over, their homeroom teacher isn’t a fan of unfair fights. During their time with him, the students will notice that this aquatic alien is more human-like than they realize. You can expect the anime to feature some incredible emotional beats that’ll tug at your heartstrings.

Furthermore, there are a bunch of characters in this anime. While it may be overwhelming for those who prefer smaller cast shows, Assassination Classroom does a fine job at exploring each of the student’s goals, personalities, and hardships within the span of two seasons.

Be warned that you won’t grow attached to all the characters present in the series. However, it’s guaranteed that you’ll end up developing attachments for a majority of its cast. If you enjoy anime with a good mix of action and comedy, check out Assassination Classroom.

This anime’s character cast is full of life and personality. The friendship between Canaan and Maria develops gradually throughout the series. Despite coming from different walks of life, their chemistry in this series is fun to watch. The side characters also have their share of standout moments. This anime’s art style and animation are gorgeous, too.

While Canaan uses some CGI elements, none of the effects look awful or off-putting. This is a fantastic action-packed and supernatural anime, assassin enthusiasts will adore.

Gunslinger Girl

This is an anime that tackles multiple different genres. It contains wonderful action scenes but features a storyline seeping into drama, sci-fi, and comedy. Despite tackling multiple themes, Gunslinger Girl manages to craft a compelling tale.

Gunslinger Girl takes place in Italy, where its Social Welfare Agency rescues badly-wounded and handicapped women from hospitals. Their mission is to give these women another shot at life by granting them artificially enhanced bodies. Afterward, they brainwash and train them as assassins who must complete heinous work for the Italian Government.

Although their bodies no longer feel human, these girls retain their child-like innocence and struggle to attain recognition from peers. Therefore, the anime follows the tragic lives of these cybernetic assassins who must follow the orders of a government that views them as menacing murderers. While the anime’s premise sounds heartbreaking, it features small tidbits of lighthearted comedy.

You’ll adore seeing the girls fighting, but get a bigger kick out of seeing them smiling. Considering the cruel circumstances they’re placed in, it’s great that the anime decides to pull away from the drama and depict its characters in joyous scenarios. The action in this anime is well-animated and the design for our protagonists’ weapons looks semi-realistic in detail.

This anime’s music and sound design are praise-worthy. The sound effects match the realistic design of the girls’ weapons flawlessly. This anime really puts you in the mindset of a soldier with its sounds and visuals. Fans looking for an assassin anime with an emotional storyline should give Gunslinger Girl a shot.,


Madlax is a mysterious supernatural anime with strong militaristic and psychological themes. It contains a gradually developing storyline with interesting twists and turns. The characters in this show have likable and relatable personalities. Many of the cast, including its protagonist, develop over time and leave a lasting impression.

The story’s pacing is a bit slow, though. Some may find its plot confusing, requiring them to rewatch the series’ final episodes to get a grasp of the information being presented. However, if you’re willing to stick with the anime’s slow pacing and peculiar plot, you’re in for a decent time. With its visually appealing gun fights, well-developed characters, and empowering soundtrack, Madlax will please you.

Madlax takes place amidst a civil war occurring in the country of Gazth-Sonika. Our tale follows two women whose lives intertwine thanks to a shadow organization. One of the females is a mercenary with supernatural skills named Madlax and a peaceful woman named Margaret Burton. These two women embark on a quest to discover the truth behind this terrifying warfare.
