In a fantasy world, fighter Tatsumi sets out for the Capitol to earn money for his starving village, and finds a world of unimaginable corruption, all spreading from the depraved Prime Minister who controls the child Emperor's ear. After nearly becoming a victim of this corruption himself, Tatsumi is recruited by Night Raid, a group of assassins dedicated to eliminating the corruption plaguing the Capitol by mercilessly killing those responsible.There is also a prequel manga called Akame ga Kiru! Zero which focuses on Akame's time as an Imperial assassin.An anime adaptation by White Fox has begun airing in the Summer 2014 season.
This series provides examples of:
Abuse Is Okay When It Is Female on Male: Esdeath slapping a collar onto Tatsumi, saying that he belongs to her, and literally kidnapping him is Played for Laughs, but imagine how such a scene would have been treated with a Gender Flip. Albeit, in the context of the setting, Esdeath getting away with kidnapping a young boy in front of an entire stadium full of spectators was likely tolerated because she's a high-ranking member of the Empire's military, not because she's a woman, not because no one took the situation seriously. In fact, the audience seemed rather shocked.
An Ice Person: General Esdeath's teigu ability. To an extent that she managed to freeze a river and a majority of a forest.
Anyone Can Die: So far, countless side characters and several members of both Night Raid and the Jaegers have been killed off, including Bulat, Sheele, Dr. Stylish, Bols, Chelsea, Seryu and Susanoo. Later on, Syura and his group murder Bols' wife and daughter.
Anti-Villain: Some members of the Jaegars especially Wave who is a type-4
Artifact Title: Although her name is in the title, Akame has recently become about as relevant to the plot as Mine. Which is to say, not at all. Hell, Mine may even be getting more screen time thanks to her currently dating the protagonist.
Asshole Victim: All of the people killed by the Night Raid deserved it.
Bad Ass: It's a requirement to survive a fight in this manga.
Berserk Button: Never kill anyone innocent in front of Tatsumi or any Night Raid member unless you wish to DIE.
Black and Gray Morality: On the one hand, you have Night Raid and the Jeagers, two groups comprised of generally nice and friendly people (barring a few exceptions) who just happen to be self-admitted mass murderers who each easily have a body count in the double digits (Esdeath and Akame likely much higher). Then on the other hand you have the Capitol, a Wretched Hive of corrupt nobles and crooked cops who regularly torture the impoverished and homeless and frame innocents for the crimes they commit. And way, way, way in the black is the Prime Minister himself, a Fat Bastard who manipulates the na´ve child emperor to ensure that all this continues.
It's outright stated in the second chapter that Night Raid aren't heroes, they are murderers. It's shown through their work that often times they have to kill people who have families or simply got in their way, like Tatsumi did. They also mention that any one of them can receive divine retribution for the people they murder. It ultimately comes down to the people who kill for the corrupt Capitol, or the people who kill to stop them.
Bloody Murder: The finger type teigu Black Marlin's secret skill is this.
Breaking the Fourth Wall: The characters sometimes deliberately do this, referencing other series in the same magazine they're serialized in. In fact, in one chapter Mine was jokingly threatening Tatsumi to banish him into other series in the same magazine with what looks like a Wheel of Fortune roulette. In case you are uninformed, this series is serialized in the Monthly Gangan Joker magazine.
Crapsaccharine World: Seems like a nice place so it can only get worse. Tatsumi is provided shelter by a family of nobles who turn out to do this so they can torture the poor country people who venture in to the big city. And that's just the surface.
Crapsack World: However, once The Masquerade is lifted, you can really see how bad of a state the Empire is in. The Capital as become a Wretched Hive, being horribly corrupt and run by a total madman. The countryside isn't much better, with the various villages being taxed into oblivion, and getting obliterated by Imperial troops and assassins when they rebel.
Cute and Psycho: Seryu. Helps lost travelers around town and nearly orgasms at the thought of slaughtering bandits.
Esdeath after falling in love with Tatsumi.
Cute Clumsy Girl: Sheele, an assassin who mistakes salt for sugar and washes Mine with the clothes while doing the laundry.
Double Standard: Rape, Female on Male: Averted. While female on male abuse is taken more lightly than it should, there have been instances of women sexually assaulting men and it's not treated as a joke.
Meaningful Name: Esdese is a wordplay on "S" desu. Schere in german means scissors (guess what her teigu looks like)
Mood Whiplash: Can go from slapstick comedy to horrifying gorn and back again in a matter of seconds. The last few minutes of the first anime episode are a particularly extreme example, featuring gruesome murder, a tear-jerking deathbed speech, Bishie Sparkle, and silly face-faults in rapid succession.
Mugging the Monster: A couple of thugs in the first chapter tries to mug Tatsumi. You can guess what happens next.
Punch Clock Villain: Esdeath may be a sadist who doesn't care for the empire's corruption, but she's a very sweet person when around someone she likes.
Bols is a massive man who walks around in a menacing gas mask, and it's his job to use his flamethrower teigu in order to burn traitors at the stake and wipe plague-ridden villages off the map, but he has a wife and daughter he loves very much.
Red Baron: Plenty. Zank the Beheader and 100 Man-Slayer Bulat are notable examples. Even some of the teigu have these: One Cut Killer Murasame, Hundred-Beast-King Lionelle, Roman Artillery Pumpkin, Demon Armor Inclusio, Infinite Uses Cross Tail, Cutter of Creation Ecstasy just to name a few.
Ship Tease: Akame/Tatsumi, Tatsumi/Esdeath and Wave/Kurome
No love for Leone? She pretty much flat-out stated that she'd "laid claims" to Tatsumi numerous times.
Vague Age: Esdeath is the only character in the Jaegars we don't know the age of. Other characters either state the range or the exact age.
Now confirmed to be "younger than mid-twenties."
Villainesses Want Heroes: Played with. It just happens that Tatsumi falls into all the criteria of Esdeath's perfect guy, and she encounters him when watching a public fighting tournament, not when in the battlefield. Because of this, the members of Night Raid are incredibly dumbfounded and confused when she snatches him up and takes him to the Capitol.
Villainous Glutton: The Prime Minister, almost never seen without something vanishing down his gullet.
