If you are one easily depressed and have your own suicidal thoughts it's not for you The story itself is breathtaking the drownings are gorges at list and it's not only sadness here but also joy but in general the story just ... has no hope in it. I will continue reading because it's to great to stop but I am absolutely sure the ending will be the werst.

I'd easily say that Gunslinger Girl is my favorite manga of all time, and probably among my favorite franchises period. Everything about it is perfect in my eyes - the right kind of dark story mixed with things that make you so happy you feel you may explode. GG gives me more emotions than anything I've ever read, and they're all over the spectrum from heart-wrenching depression to the biggest smile you might ever see me wear. The fragmented storytelling is the essence of awesome, and the series FORCES you to think hard about it. The way it's written keeps you on your toes begging for more, and it's got the best re-reading value I've ever witnessed thanks to the non-linear-yet-linear format that conceals as much as it lets known at all times. Truly an awe-inspiring series that utterly humbles itself.

Unlike other commenters here, I don't find Gunslinger Girl depressing. Yes, it's very sad in places, but what shines out through the story is the sheer will to live exhibited by the girls: they triumph over what's been done to them by enjoying the everyday things around them and simply by being human. I found Gunslinger Girls a very interesting exploration of human character in all it's good and (very) bad aspects, all wrapped up in a great action story and accompanied by some very fine artwork. So far (first 5 volumes) it's been an addicting read. Recommended.

This is one of the most depressing manga i have read, and its worth reading, check it out.

This bittersweet series does a good job of making you care about the characters. Definitely one that I will persue.

Interesting yet depressing. Check it out if you like manga like chobits.
