Seraph of the End: Owari no Seraph

[KrayZ33]

edit: ugh well, whatever.

Just one thing, it should've been impossible to sneak up on him in the first place, since he can feel the intent to kill from miles away (tower scene)

Superpowers (and that includes superspeed, the sixth sense and able to dodge stuff comming from behind in less than 0,00x seconds) sure are inconsistent. Just look at how Yuu was able to get his hit in.
*THATS* announcing an attack from behind (screaming and shouting before he even went in), and it's the killing blow of all things.
