I've come up with a few theories. 1: He just wears it to look cool, and it has nothing really under it but a normal face. 2. Some sort of scar maybe? Some deformation? (Kinda disagree with this one considering that Ramen Girl LOVED him when he ate his ramen) 3. Maybe he has a Cursed Seal or something...meh just a theory. Considering that blue...whatever it is covers up mostly his whole body. 4. Maybe some markings or something on his face? Looking for more... And for those who have seen 101... Spoiler: ...this is besides the point that there is another mask under it, I'm saying like to the skin and stuff. These are just my theories, just saying what I think. xP So please don't flame me saying they're gay.
