Ao no Exorcist, Hunter x Hunter (2011) Recommendations
The exorcists have special privileges, getting to go wherever they want to with the keys. The hunters license is like a passport to anywhere. Each group goes on adventures within their group and they form friendships, despite dark adventures. The plots draw the viewer in.
They're both about a kid that goes into an adventure, makes friends, encounter enemies, grow stronger, etc. Oddly enough, the characters are bound to one type of many "magical power" (Like Spec'ing in an RPG). The thrill in HxH(2011) comes slower than Ao No Exorcist, but I will still recommend it before the other.
Hxh is more darker than ane but both of them have got similar main character. Rin and Gon are helpful, funny, brave and.... not too smart
