 If you liked
D.Gray-man

 ...then you might like
Shingeki no Kyojin
|
If you like the dark and depressing mood of Shingeki no Kyojin (underdog heroes trying to battle monsters much stronger than they are), then D.Gray-man runs along the same tile. Both have main characters constantly trying their best to defeat the almost immortal villains. And all the deaths around them...
