Socrates in Love - Let me tell ya, I'm not easy to cry. There have been only 1 anime and 2 manga that have made cry and this is one of them. This was such a heart breaker. You know what happens in the end cause they tell you in the first chapter but still managed to make me cry. A surprising thing though is that I cried on the 1st re-read as well. Usually impact is lost when re-reading it.
I don't know about the saddest manga, but I know a few that made me cry. The first is Video Girl Ai, and always for the same reason, that is
when Natsumi dies T_T She was my favorite character in that story
The second is One Piece, Arlong saga, the famous Nami scene (where she's crying and begging Luffy to help her, I just love the raw emotion she's showing).
I know I have another title, but I can't remember it at the moment.
Immortal Rain made me cry; book 4 was just so sad! :( Fushigi Yugi also made me cry, and I think book 4 of that made me feel the saddest too.
I'm not sure about other manga that have made me feel sad... A.I. Love You 8 made me cry, but it's not really sad overall.
I havnt read many sad mangas, but one sad manga i have read is a 1 volume manga called Hoshi no Koe. Well worth a read if you like sad mangas.
Oh and one more manga i forgot to mention, is Bitter Virgin,drawn by the mangaka of Girls Saurus. Its a pretty tragic manga, which picks off right from the first chapter, so you get the feeling of sadness really early on, and it doesnt get any happier from there. Its 3 volumes atm and still ongoing.
1. Chrono Cruasde, the neding was really sad, but still, there couldn't have been any other ending (eccept the anime ending) or a happy ending, 'cause that would just ruined the whole series. (At least that's what I think)
I'm currently reading full moon, but missing volume 4 and 6, but damn, it's so sad, even when I've just read the 3 first volumes..
Confidential Confessions is just really depressing.. in a good way...
boku no hatsukoi wo kimi ni sasagu < probably the saddest thing i have ever read, there is only 5 chapters translated so far to my knowledge(?) and i am eating the angst up :_( it should turn out to be a really good one
I really hate sad stuff, so I've picked up a habit of unintentionally avoiding anything branded "sad". The only sad manga I've read was Ai Ren. Never again would I want to see something similar to this. Sadness is a strong emotion indeed and leaves even stronger impact. I bow in front of any seriously sad manga, because to evoke real sadness in reader, the manga must be really amazing, but still, sadness is not something I like to feel, so I'd rather avoid these kinds of mangas...
I don't recall the "saddest"one I've ever read, but I do recall sobbing over Forever Honey. It's the only one shot (yes, one shot) to have ever made me cry, and one of only 4 or 5 manga that garnered tears. It's not a depressing sad, but a bittersweet sad.
Destroy. Destroy. Destroy. Slowly, completely, gently beyond comparison, cruelly to the point of numbness, I'll violate your life. That's right. The instant I rip off your limbs, tear open your rib and pull out your intestines, biting into your neck as you scream in agony, chewing through your eyes as I ignore your pleas for mercy and spreading your brains on the ground like butter!
