Guys, would you have recommendations for a LONG (finished or not) manga series, that would be available for online reading ?

Not the hentai stuff that I’m sharing here on, I’m talking about the non-porn stuff ;)

I recently caught up with the latest chapter of Magi, loving every bit of it !
And here I am, now, left without any long serie to read and discover. I’m re-reading Berserk, but I’d love to discover new GOOD and LONG series to read, either finished or still ongoing…

I’m writing a bit more about it in the rest of this post, if you have suggestions, I’ll be grateful :)

My requirements, my tastes, are :
– not shoujo/smut/josei (well, there are a few of them that I like, like Oishii Kankei, but they’re exceptions)
– Original seinen and shonen not going the DBZ/Bleach/Naruto way (like Magi above, Akumetsu, Berserk, Vinland Saga, Gunnm…) is perfect.
– Also a lot into sci-fi (rather hard science than space opera : like Planetes, Uchuu Kyoudai, but a parody like Those Who Chase The Ageha is awesome !). Not against moving/unique stories (Yokohama Kaidashi Kikou !).
– On the rare occasion, mystery manga (like Death Note, or the mangas by Naoki urasawa) when this isn’t always the same repetition.
– Nasty liking for “all shall die” stories like I Am A Hero.
– Or crazy funny WTF fantasy (like Gintama, Binbougami Ga). Hilarious shit like GTO or Needless is always more than welcome.
– Lastly, there are “alien to real classification” series that I adore, like Hunter X Hunter, Toriko, Bambino, Yotsuba-to, Oyasumi Punpun, the mangas by Mori Kouji (like Suicide Island, Holy Land)…

See, that’s pretty varied tastes :)

Below, I’m pasting a link of all my current followed manga on (exporting it was a pain, I tell you). You don’t need to recommend these ;)
I don’t say I’m reading every one of them as soon as they’re released (far from it), but if they’re in my follows, that means I like them a bit, a least, and I don’t want to forget about them ^^ There must also be a few missing mangas from that list, especially the old ones, but, hey, that’s already many.
