Okay FIRST OFF. More November birthdays! Alex was on the 14th, and Chad was on the 17th. So happy birthday you two!
As for the other two pics, we have Persephone cosplaying as Kanaya Maryam from Homestuck and then Shuuhei WITHOUT HIS BLINDFOLD. Just to make things clear, THIS IS CANON; it happens at some point, and it is AWESOME.
So anyway, enjoy! : )
