I'm only in the beginning of the manga now, as though many have said after the first few chapters its basically the same as the anime, rather than start off from where the anime left off, i felt it best to start from the start just to make sure i not only refresh my memory of earlier events but also to make sure i don't miss any minute details that might have not been included in the anime. I mostly only read it on my way to and from work/school on my Ipad so it will still be a next day or two before i reach where the anime finished (around chapter 150 i believe i've read somewhere), so i'm still a few days away from the end.
I do thank you for replay to, and your input is greatly appreciated, as now i know of at least a few things i should look for and make sure to pay very close attention too. I am also glad to see that the manga will indeed address some of those issue i have, usually by now i would find my sleep quite bored and disappointed with many anime i have watched, only really sticking it out to see how the story ends/plays out even though by then i'm pretty sure it would be crappy. However i find my self loving every bit of D Grayman (just wish that the generals were more battle active before the anime had ended especially Tideol, even while the battle with the earl was going on in Edo he seemed not caring in the anime, until lenalee innocent acted up again, and he thought it might be the heart), and can't wait for more to see how it all plays got and gets wrapped up, truth be told i'm kind of trying to read it very leisurely so as not to get to the last available chapter too quickly, though i am dieing and tempted to just spend all day and night reading through it.
