He's considerate, diligent, and a model convenience store worker... but just who is Mutou? And what exactly is up with his head?
Denied of the chance to have my face seen...
...يمتنعون عن فرصة رؤية وجهي
Nicht mal kann man mein Gesicht sehen.
Nadie puede ver mi rostro…
Nadie puede verme la cara…
Personne ne doit voir mon visage.
Privato della possibilità 
di mostrare il mio volto...
Ninguém sequer vê o meu rosto...
Моё лицо не могут увидеть...
