Episode 7 of both series convinced me to make a recommendation. If you're looking for something with a similar story-line or genre, I suggest you skip this one. YOI is sports and slice-of-life, while No.6 is is some kind of dystopian scifi action anime. However, when I watched YOI, I felt a familiar vibe and at first I couldn't really point what anime this reminded me off, till I scrolled past No.6. Both series have a heavy focus on the relationship and tension between the main-characters. Imo, No.6 was the only anime I knew, who found it's place between 'gay baiting' and official Shounen Ai, but I have  read more

The stories are based around a future with high level technollogy that allows a select group of huimans to live in peace. Yet there is a dark secret behind the societies that they are living in. Both happen to feature young males whose perspective of the world is naive, not to mention innocent of the way the world looks. But when someone suddenly shows up, a person very mysterious, suddenly, their lives end up being turned upside down.

Both shows have a continuous, non-episodic structure and are about closed societies whose residents are mostly kept from the real world. The main characters learn in time the horrifying secrets of their beloved home place and try to rebel against it. Both stories start with young heroes that grow older as the show progresses and show an open approach towards same sex romances.

Both anime tell a story about a futuristic world in which everything is "perfect". But it's too perfect, and in both series you'll find out the secrets that the organizations keep from the ordinary people.

Both involve a deadly virus that seems to be used by the government in both series to rule undemocratically. They both feature government corruption, rebel groups and take place in a futuristic setting. Yuki Kaji voices both Shion (No.6) and Shu (Guilty Crown). Both aired on noitaminA, and both have many flaws which have lead to both being called the worst of noitaminA.

Anime that feature the dark side of society. Lots of action and lots of tragedy. Both have a "protagonists against the world" kind of vibe. In both anime the main characters meet by chance and spend time together, eventually falling in love with each other. Their relationship is never really mentioned or the main focus of the story, but it's clearly there as they face hardship and sorrow.  
report Recommended by MaahHeim
Both anime talks about two friends who wants to overthrow the existing government. Nezumi from No.6 have the same reason as the two protagonist in Zankyou no Terror: revenge while Shion is more similar to Lisa. The atmosphere, general feeling and character development is similar in both anime.

Very similar settings. No. 6 is like Ergo Proxy in cuter, brighter and more colorful, unfortunately also more childish and simplistic. Ergo Proxy is darker, cooler, weirder, more mature.

Both series are based on different novels that use a similar post-apocalyptic setting where a community of people forgotten by society lives outside a fortified utopia.

The relationship between the two main characters are pretty similar. If you liked Nezumi and Shion's relationship then you should like Duanmu xi and Yang Jinghua's.

The beginning of the story is the same and Sion resembles to Jomy Marcus Shin. 
report Recommended by BelovedUsa
Both animes are about persons fighting a system they're captured in. Both systems are inhumane and cruel. Also the males have a deep friendship. No. 6 is not shounen ai romance but still has a BL subplot. Owari doesn't have such so far and I guess it won't since it's shounen. Owari is of very high quality (animation, music, atmosphere, story) and can bring your tears out. No. 6 has a very good manga/novel but the anime (is a rather stumpy) can't compete with the manga/novel in the slightest. Although Owari isn't shoujo it can be watched even if you prefer shoujo over shounen.

Akatsuki and Chronos seem to have the same concept: the bigger and better city. Plus, Shion and Nezumi can easily be compared to Lag and Gauche.

Both series take place in a futuristic future society. There are supernatural phenomenons and mysteries. Both main characters are fugitive criminals. A secret society/organization is after them.

The plots aren't the same, not even close, but the 'feeling' you get while watching them is the same. Dark drama, sadness, fighting, blood spillage, deaths and fighting to survive in a broken down civilisation with only 'hope' as your guide. Also that both animes have secrets about the world that keep you guessing to the very end. Also the bond between the characters are the same.

Protagonist starts off as a nerdy and naive cinnamon bun, has his eyes opened to the unfairness of the world and goes through some trauma that turns him into a white haired sinnamon roll. Things happen, I cry. It's like TG's less traumatising gay cousin.

Well... + There is a mysterious disease that spreads fast and kills people. The government is doing their best to hide it. + There are two main characters, both guys. One is extremely active and loves to fight while the other one is more reluctant. + The two main characters were friends for a while but then get separated for quite a long time. Later, when one of them is in danger, the other jumps in and saves him, reuniting them. + Deals with post-modern society technology/skills. + Studio Bones and well this one is for the yaoi fangirls... + The two main characters are totally shippable.

Both have sci-fi and a sort of futuristic feeling. Both involve as main protagonists, a lively girl who loves the main protagonist (a white haired boy) and that boy makes a sort of "best friend" where they are always together, and the three of them try to find out the truth behind the mysteries involving their home planet/city.

Both also have a similar feel. Both have to do with a 'childhood friend' and such.

Trying to place the similarities between the two shows into words is honestly complicated. In part, I don't want to give away spoilers. Seemingly dissimilar are these two series except for the same-sex content which crops up, that's really not the only draw. Perhaps then it is the draw of the characters, and how each is almost like their own book? Or the fact one is on the edge of their seat wondering what happens next. Perhaps words were easier to put down than first thought.

INCREDIBLY similar to this anime. The human race has retreated behind a wall, and are now being attacked by a threat that could wipe humanity out if they allowed. Main protagonist has to figure out how to stop it. Early in the series they are affected by said threat, but not killed.

They are both a type of Shounen-ai, with deep friendships between boys and Nezumi kinda reminds me of Luka from Uraboku (Uragiri wa Boku na Namae's short hand version name) because they both are honourable, they both try to protect a weaker, soft hearted and almost clueless boy that they are friends with, they are both in love with the other boy, despite the fact there arent any confessions.... both anime are fantasy/horror based too with interesting side characters....

Even though No.6 is a Shounen-ai, I have to say that we have very similar characters not only as personality but also suprisingly as physically! In both shows, notion of love and friendship captures you so fast!

Similar world in both shows (Not so much No. 6 itself but the west block strikes me as kinda similar to the village in Canaan) Also there are a lot of yaoi undertones between Negumi and Shion in No. 6 which are kinda similar to the yuri undertones between... Every character in Canaan.

The plots aren't the same, not even close, but the 'feeling' you get while watching them is the same. Dark drama, sadness, fighting, blood spillage, deaths and the search for the truth in their harsh world with a little romance mixed in. In No.6 case, the romance is more of a 'bond' between the main characters (cos they're both male) where Romeo + Juliet is about about their love and passion for each other - based on the original of course. I also think that the animations are very similar; the way they move, fight and the way the characters are drawn. So even though the plots are  read more

They're both light shonen ai where the bond between characters is very important, but isn't the main conflict of the story.

The setting in both includes wealthy cities surrounded by poor areas, in the future. Both have 2 male leads who are friends, and are in trouble with the authorities from the cities, so they are hiding out in the ghetto. Innocent Venus is a bit more action-filled. Both have nice animation and are quite short.

Future cities where the lives of people seem to be completly all right, only for there to be some dark, deep secret. The art style of both series is along the lines of gothic. There is also the slight element of school, whereas school is mentioned, even though it isn't very important.

While this may not seem like an obvious pairing, by the end of Oushitsu Kyoushi Heine I felt that No. 6 had a very similar mood. The princes are Shion, bright in temperament but oblivious to the people around them. As the princes grow, so did Shion--through experiences that wouldn't have been experienced until leaving the comfort zone. Heine's past and Nezumi's present offer the same reality: Things are much more complicated and much darker than they knew. Both the princes and Shion had to decide how they wanted to approach the trials ahead and tackle them similarly. There  read more

Both shows tease viewers with shonen ai that will inevitably never come to be. But aside from that, both series have unique world-building and carefully crafted character relationships. Although their settings are starkly different, with MDZS taking place in ancient China and No.6 being set in post-apocalyptic Japan, these shows will compel you with their array of comedic, heart-stirring, and tragic moments. Moreover, don't let the Chinese audio put you off from MDZS! It may take some time to get used to it, but C-anime's differences add a fresh quality and charm to the show.

Both animes have a serious dark haired character that takes care of a supposedly ditzy guy. Although in OreFuro the other MC is actually an airhead. Both animes have a strong BL feel, with No. 6 actually having a canon romantic element, OreFuro is just a HEAVY (I mean heavy!!!) bromance.

Fateful encounters cause sadness at times. Both settings are different. But characters are quite similar. Especially Main Characters. Story progress by two pair. Zwei and Ein. Shion and Nezumi. Their relationship are almost same. Both focus Drama than Action. Friendship, Frustration, and trust are part of theme. Phantom is bloody and tragedy in modern age. No.6 is complicated and devastating in dystopia. OP and ED songs are aesthetic. Phantom's first OP and No.6's ED are goosebumps. High artistry. Both brings endless surprises. Just see it.

Im assuming you like 'boys love' anime so if you do, this is for you!

Nezumi and Shion resemble Daryun and Prince Arslan. Their individual personalities, their companionship, and even the way they look, it all seems uncannily similar.

Tragic circumstances bring the main characters together to fight for their lives and for a better future..

If you like the shounen-ai aspect of No.6, then you will enjoy Gravitation. Gravitation doesn't have a tone as serious as No.6. However, there is a dark past to both Yuki and Rat which affect their relationship with the main character. Gravitation will be more of a comedy and a little silly at times. But if you enjoy one show, you are likely to enjoy the other.

Distant future, discrimination, action, experiments on human beings, bishounens as main characters - this is what you'll definitely like in "Cluster Edge" and in "№6" It will be to your taste.

Eventho on the surface these two titles have nothing in common: one is mecha [Fafner] and the other is dystopian fantasy [No. 6], the reason why I'm linking the two is because of the very gay [but not really gay] subtext of these titles.

Both are Science Fiction anime mixing futuristic tech as well as showing desert-like wasteland environments, and focus on the moral dissonance between optimism and cynicism, angels and devils, pacifism and practicality. In this respect Nezumi/Rat and Wolfwood both act as the cynical ones, who have disdain for Shion and Vash's optimism and pacifism, but are ultimately converted. They have very different stories, but both portray a lot of the same themes of peace and compassion for human life, the value of relationships between people, and humanity's capacity for both great good and great evil.

Have very different characters and style but somewhat similar stories and settings in the sci-fi genre. They both take place in a post-apocalyptic world, No.6 in a city built to be a utopia with a wall to keep the rest of the world out, and Big O in Paradigm, a city where the rich live in domes, and few know about the cities outside. Both settings have dark secrets the main characters must uncover, and in doing so learn more about themselves.

Both are Science Fiction stories taking place in futuristic cities, with border-line shounen-ai bromances between the two male main characters. No.6 is shorter (11 eps) and much darker with younger protagonists, while Tiger&Bunny is lighter and has a two-part plot (20+ eps). In both the spotlight is on the two male leads, one of who's goal is to get their revenge, and how the two grow closer and come to understand and value each other.
