It's pretty much cannon. But the relationship they have is not sexual at all. It's only platonic in this case. (Meaning that it's very intimate but never sexual)
Now they DID Kiss in both the novel and anime. Where I live that's considered 'gay', but to me it's more of a close friendship kind of kiss.
No.6 is a mild Shonen-ai. Not really gay but not exactly straight.
It is quite obvious in the manga and the anime that they are cannon, but in a tasteful manner. Their love is more than skin deep, and their relationship has been tested mutlitple times, only to be proven that it's for real. Although some peole like to claim they're "just close friends" or that they have a "brotherly" relationship, I find that hard to believe. I know many guys who have close friends, but never ever would they kiss them, especially on the lips, even to prove a point. Some peole just don't want to label No. 6 as a yaoi or shounen ai, becasue they are either against such things themselves, or they don't want to put a "taboo" label on it.
Here's an image from toi8, the people who did the offical art for the anime.
So yeah long story short, they're an item : )
Their relationship is definitely more than platonic, but it's not overly sexual either. They have strong feelings for one another and Shion actually changed Nezumi's way of life. Their love runs very deep <3
Not really. It's only everyone's imagination. They do kiss and they do LOVE each other so they might be gay, but they never has sex, so I'm not sure.
The manga and anime are both rated YAOI, so yeah,...
Well I don't think "Gay" is the proper word for it, since they r both men and inlove, then yes they r gay, but their Relationship doesn't really look like the whole "Gay" hype thing, it's not like they r only interested in men, talk funny and act exentric, they really just fell in love with each other and just didn't care about the genders.
So yes, the only word we have for it curently is the word "Gay", but the Relationship was, in my eyes, something abit different....
Of course! Best friends don't give each other goodbye kisses! I'm so happy to see queer characters who's perpous isn't to simply be queer. I wouldn't consider it a yaoi though, since it's technically not a romance anime. Though I do believe they are canon.
They are. I love that it's not just a simple crush or attraction, that's why a lot of people are confused. Their love is more than skin-deep, it's more than in a 'I want your body' but in a deeper sort of way that doesn't even need the 'I love you' or 'I want to make out with you' (though they did kiss). That's why I really love this couple, that they don't need to clarify their love, it's there already. And if you REALLY need proof besides the kisses they gave each other (though I don't really see the point) they dance. And after Shion kissed him, Shion said: That wasn't a kiss of gratitude, that was a good night kiss. Shion went outside, and Nezumi had thought: A good night kiss, huh? You're such a liar. I literally squealed when he said that. So if you don't realize what that meant, I'm so sorry, please go see a therapist. You're so dense.
