D.-Grayman

It's a pretty well-known series already, but it's nevertheless underrated. Especially since the anime had ended a little early and the manga has switched from weekly to monthly a few months back. But even so it is one worth adding to the list.

Set around the end of the 19th century in Gothic Europe, the world of DGM is infested with disease and despair that poisons the mind and hearts of the people. A religious association known as The Black Order has been on a centuries-worth mission to purge the world of this enigmatic darkness that threatens to dissolve humanity off the face of the earth. Their primary enemy that is responsible for this constant threat is the Millennium Earl and his band of sorrowful creations known as Akuma.

Only a group of chosen ones known as the Exorcist can defeat the Earl and his enslaved toys, using what they call God's weapon for the sake of humanity-Innocence. A young boy named Allen Walker enters the Order in the hopes that he can use his Innocence to not only save humans, but the souls locked within the Akuma as well. As he goes through countless missions with his friends, experiencing every hardship possible that challenges their will to fight, Allen continues to learn more about the world in which he was born into and the destiny that drives him to hidden truths about himself.

I found this one on a review a long time ago, and was intrigued by the artwork. I started off with the anime, but then eventually switched over to the manga at some point when I found that there was more in-depth info there. It's great to watch Hoshino's skills progress overtime and how the plot continues to thicken as she progresses with each new chapter. The anime, both original and dub, are really great too and are recommendable. Although it cuts short because of the hiatuses from the previous year(s) and has a few fillers here and there, it's still pretty good. And since it ends with a somewhat open ending there is a chance it could return-small as it may be.

It's definitely one of my favorites, containing that gothic element and Tim Burton-ish style of characters (particularly the bad guys). Sure it's a monthly series, but Hoshino really knows how to deliver by making each subsequent chapter chock full of suspense and invaluable info that fleshes out the characters and plot significantly almost every time.
