Hey, guys welcome back to Kaizetsu.com. Today we are going to provide you the list of Anime which are very similar to anime named 91 Days.
Short introduction to 91 Days:
Moritaka Mashiro feels as if life is passing him by; with no dreams or motivation, he trudges through day-to-day life. One day, after leaving his notebook behind, he returns to school and finds the smartest guy in class, Takagi, waiting for him. Takagi is happy to return the book, but on the condition that Mashiro agrees to become a mangaka with him. Though Mashiro initially declines, he soon reconsiders when he discovers that the girl he likes, Azuki, dreams of becoming a voice actress. And after promising that she can have the lead role if their manga is ever adapted into an anime, he suggests that they get married once they are both successful! Shockingly, she agrees to the proposal and Mashiro and Takagi embark on their quest to become manga artists.
10. Kuroshitsuji (Black Butler)

Description: In Victorian England it is commonplace for the rich and wealthy to have a staff, led by a head butler, to run their households; the Phantomhive Estate is no different. The young and demanding Count Ciel Phantomhive, child owner of a toy company, lives in the grand countryside manor. Sebastian is his head butler, and the epitome of perfection; he effortlessly and gracefully completes his day-to day chores and fixes the countless mistakes of the other employees. However, whilst on the outside all seems prim and proper, a more sinister secret lies just beneath the surface. Sebastian is in fact a demon bound by a contract with the young count; he will loyally serve and fight for him in return for his soul.

Both of these are set around the same time period, they both have main characters that are pretty emotionless because of their past and they seek revenge. Like in 91 Days, you can’t trust anyone. It seems as if everyone has evil intent and both have a lot of violence and are pretty dark. They both have some funny moments though (especially Kuroshitsuji).
9. Death Note

Description: Have you ever felt like the world would be a better place if certain people weren’t around? Such grim daydreams might occur when watching the dismal daily news, but on one fateful day, Light Yagami finds that these daydreams can become reality. By pure happenstance, he comes across a black notebook entitled “Death Note”, whose text within states that whoever’s name is written on its pages will die. With the aid of the death god Ryuk, Light takes it upon himself to rid the world of its corruption, ushering in a new era of purity one death at a time. But as Ryuk foretells, Light’s actions will not go unchallenged…
Number of Episodes: 37
Release Year: 2006 – 2007
In all honesty, they’re not super similar. However, they both have two main characters who interact with each other frequently despite being pitted against each other. Along with this, both anime deal with a lot of deception and moral analysis. I really liked both shows, mainly for the reasons listed in both cases, so if you like one of them and haven’t seen the other, give it a go.
8. Phantom: Requiem for the Phantom

Description: A young man awakens in an abandoned warehouse with no memory of his past. As he leaves the room and ventures further into the warehouse he is attacked by a girl in a mask; she tells him that in order to live he must come at her with all his might.

For three months, Zwei is trained by the girl in the arts of assassination until he has just one final test: to kill a living human being.
Number of Episodes: 26

Both are involved with the criminal underworld of America, both main characters have had something taken from them.

As tragedy touches the lives of those around him, can Albert’s only recourse be to wait and hope?

Release Year: 2004 – 2005
Both shows have an intelligent main character in the case of Gankutsuou it is the of The Count, the main antagonist of the series. Like in 91 Days he is a manipulator out for revenge. If you enjoy clever puppet master type stories such as 91 Days or death note featuring intelligent characters than this is a masterpiece that you will surely enjoy.

5. Joker Game

Description: In autumn of 1937, as the coals of World War II are beginning to smolder, Lt. Col. Yuuki of the Imperial Army secretly establishes a spy training organization called the “D Agency.” Those chosen as members of the agency, in opposition to the national trend toward reverence of native-born soldiers in the army, are civilian university graduates who pass the superhuman selection test with flying colors. Under the resourceful Lieutenant Colonel Yuuki, they learn not only how to work with gunpowder, wireless communications, vehicles, and airplanes, but also various skills essential for spies…
Number of Episodes: 12
Release Year: 2016
Both shows take place during the early 1900s and show the seedy undercurrent of society during that era. Containing similar art direction, color palettes, and sound mixing, these titles feel like they share the same universe. Taku Kishimoto is also credited for his series composition contributions on both titles as well. They’re titles that gravitate away from the usual anime trappings, taking more influence from the world of cinema instead. If you enjoy the tone and atmosphere of one, there’s a high chance you’ll like the other.
4. Code Geass: Hangyaku no Lelouch (Code Geass: Lelouch of the Rebellion)

Description: In 2010, the Britannian Empire enslaved Japan using powerful mecha known as Knightmares; in the aftermath Japan was renamed Area 11, and its people began a hard and terrible existence.

One day, in the middle of a terrorist attack, Lelouch meets a mysterious girl who grants him the ability to control minds. Can he use his new power to fight for freedom, or will his hatred twist his good intentions into mindless acts of vengeance?
Number of Episodes: 50
Release Year: 2006 – 2008
Avilio is very similar to Lelouch, both are very clever manipulative tacticians, both seek for revenge for the death of their loved ones, although the atmosphere of both shows is way different, regarding the main protagonist these anime are kinda similar, if you like Avilio’s character then you will totally love Lelouch Vi Britania.
3. Gangsta.

Description: In the city of Ergastulum, a shady ville filled with made men and petty thieves, whores on the make and cops on the take, there are some deeds too dirty for even its jaded inhabitants to touch. Enter the “Handymen,” Nic and Worick, who take care of the jobs no one else will handle. Until the day when a cop they know on the force requests their help in taking down a new gang muscling in on the territory of a top Mafia family. It seems like business (and mayhem) as usual, but the Handymen are about to find that this job is a lot more than they bargained for.
Number of Episodes: 12
Release Year: 2015
Similar in tone when comparing the brutality and the harsh reality of the main protagonist lives, work, and overall society each where given. Also, both main characters were given “unfavorable” cards in their lives but decided to challenge them in an act that might seem futile to others. But in reality, it is not so much the act of rebelling but the significance of said rebellion which is expressed in each story.
2. Banana Fish

Description: Nature made Ash Lynx beautiful; nurture made him a cold ruthless killer. A runaway brought up as the adopted heir and sex toy of “Papa” Dino Golzine, Ash, now at the rebellious age of seventeen, forsakes the kingdom held out by the devil who raised him. But the hideous secret that drove Ash’s older brother mad in Iraq has suddenly fallen into Papa’s insatiably ambitious hands–and it’s exactly the wrong time for Eiji Okamura, a pure-hearted young photographer from Japan, to make Ash Lynx’s acquaintance…
Number of Episodes: 24
Release Year: 2018
Mafia-centric, takes place in America, a revenge story, nothing to feel good about but lots of reasons to cry – if you are into that, then you will love them. While 91 Days deals mostly with drug crimes and violence, Banana Fish touches on much heavier topics like sex trafficking and pedophilia, never graphic in nature, it’s more a drama-thriller with less violence and younger characters than 91 Days, which shows gruesome murders in detail. Another similarity is the very realistic depiction of the mafia, there is no romanticization or glamour to it, if you are searching for that then neither of them will be to your taste. One aspect to note is that Banana Fish features a gay couple, but it’s never up in your face and can be easily overlooked, while 91 Days has no romance or even vaguely non-platonic relationships.
1. Baccano!

Description: It’s the 1930s, and Mafia groups fight for supremacy in American cities. Young Firo joins the secretive Camorra group; a meek street boy, Jacuzzi, finds himself the leader of a gang of thugs; an alchemist is producing a liquor of immortality, and a homunculus tries to retrieve it; and upbeat thieves Isaac and Miria head to New York after failing to strike gold in California. They ride the novel train, the Flying Pussyfoot, across the continent. However they find themselves embroiled in a ruckus caused by gangs, terrorists, serial killers, and others as multiple stories intertwine and unfold on this fateful ride. All are haunted and hunted by the legendary Rail Tracer…
Number of Episodes: 13
Release Year: 2007
These are two period pieces that showcase very similar eras of American history (Baccano! takes some creative liberties with that though). They feature excellent character drama and development, and both feature similar themes of revenge and deceit. They have great soundtracks that really capture the era. Bacanno is a bit more ridiculous and goofy, especially a certain pair of characters, but it really helps to balance the mood.
There are others also that are similar, but these 10 are far most Similar To 91 Days. Consider subscribing to our mail list to get notifications about all news about anime, also join our anime discord server to talk with other anime fans. Discord Server
