The story of No.6 tells us about false utopia, universal control, which is like in Terra E... Also the main character of the manga is very similar to Shion.

Although the plot is completely different, the relationship between two male characters was extremely similar. I got the same vibe from Nabari no Ou as No.6 while I was reading it. Both manga have unique characters and refreshing stories.

Both series are set in a future where the world has become uninhabitable except for a few select places. Privileged people live within a walled city where they are ignorant to the lives of others living in the slums outside. In No.6, Shion is one of the privileged living in the wall. In Mother Keeper, Ricalna is one of the rebels living in the slums outside. In both series the protagonist ends up on the other side of the wall and learns that life there isn't what they expected and that everything they have thought to be true might be a lie.

Both manga are dystopic stories centered around pretty boys. Both series center around the relationship of two male characters in this setting, though in Inferno that relationship seems much less romantic. The atmosphere is the same.

When reading No. 6, I couldn't help but think about Tegami Bachi where there is a centralized government with a main city while the poorer people live on the fringe outside of a barrier and only certain people can pass through. Both stories involve lovable ((white haired)) characters investigating mysteries of their world to discover brutal truths behind them, and both can really fill you with feels. Also, you don't want to mess with the insects in either of these manga //laugh// The art in both is really great, too!

For anyone who misses No.6, I heavly recommend Harukaze no Etranger and Umibe no Etranger. Specially for the ones frustrated with No.6 lack of relationship development.

- Both shows the relationship between two young men who grow with each other
- Similar art. For a minute I thought it was the same mangaka
- The fluffyness of characters, cuties.
- The personality of Mio remembers Shion's personality
- Shoujo manga

What they don't have in common:

- No.6 is shonen ai and Harukaze is yaoi (has sex scenes), but the last don't focus on sex like other yaoi does but instead it  read more

- Shion and Shu are wimpy protanonists but they have a subsequent U-turn in terms of personality;
- Nezumi and Inori are mysterious deuteragonists with the power to impact people's lifes with their singing voices;
- Mysterious life-treatening viruses;
- Futuristic/Post-apocaliptic/Dystopian settings;
- Similar genres (Drama, Sci-Fi, Psychological);
- Romantic subplot between the main characters;
Both series have dark atmospheres, dealing with government corruption, rebellious groups (a.k.a. La Résistance), moral dilemmas, some action, great character development and both manga have alternate (non-canon) endings in which the characters that perish in the original story survives, making both adaptations less impactful than their respective  read more

No. 6 and Pandora Hearts share in common an intriguing, charming eccentricity and focus on genuine character relationships. The art in both is mind-blowingly gorgeous, and both have plots that seem simple at but become much more complicated, interesting, and layered. 
reportRecommended by ShadowMelon
Like No. 6, Golden Days has a love story between two boys that is not the focus of the plot. The plots of both are suspenseful, though they are in different genres. Both romances are more emotional rather than physical. They also both have female characters who play important roles. 
reportRecommended by Kaiko
Nezumi and Shion are like Fon and Jaques in certain ways. Fon and Nezumi both lost their families tragically. All the characters have learned that there are still people willing to help other people even at the detriment of themselves. There's also the theme of geniuses in both series, and the idea of a place that may seem ideal on the outside but is really corrupt underneath. Both have the main characters changing each other in many ways, and almost the same level of BL and darker themes. 
reportRecommended by Chouninatte
Both are about two people solving a mistery and at the same time learning about themselves as well as one another. NO.6 is a lot darker though. 
reportRecommended by Hattress
- They both start off in a closed off place/region where everything is being controlled and is considered "perfect". - The main characters both know that where they live is a false utpoia - They run into a wanted criminal and end up saving them and by doing this it changes their lives forever...

Though the stories in themselves aren't really similar, the main characters cross over nicely.
Allen Walker is like Shion with the scar on the same side of his face, brown hair which turned white after a near death experience, and his happy, innocent demeanor despite what he's been though.
Kanda Yu is similar to Nezumi with his bluish-black hair always worn in a ponytail (though longer), his irritation at how naive the main character is, his exceptional ability to fight, and his unknown origins. 
reportRecommended by CatHime1
Two young men fight against a corrupt organization. One is ruthless and intelligent, the other is forgiving and kind. There is a lot of guns and action mixed with scenes of character bonding. Both have a large cast of characters. 
reportRecommended by Kaiko
Both these mangas are quite different; no.6 is a dark story about a false utopia, Seven Days is a Love story. Both are good in their own ways. What they have in common is how they portray queer characters; with respect and without fetishizing them; good writing in this part.
