d.gray-man
A manga that hits you like a brick wall every month, and if the author doesn't get sick or punch her hand, you get more pain, more tears, and more confusion.
'I just read the new chapter and I feel like I got hit by a train and a pizza.'
'This manga is so bad it makes my brain hurt and my lunch taste like sadness.'
'I read it and now I can't stop crying, my eyes are like fountains.'
