Not gonna go into detail plots and stuff but :

Soul eater <~ fantasy fights, unique plot , it's a bit slow on it's introduction but gets really good after it's done through that stage

D.greyman
Similar to blue exorsist where the main character goes to a school type of place to learn and improve his powers bla bla bla


Magi
2 season anime
Unique plot
Very interesting + mysterious story
Fun adventure
Fantasy/magic XD
probably one of my favourites.


Code gease
You mentioned death note and most of the people I know that liked death note also really enjoyed this one so you might want to give it a go
