( Is this possible to be deaf and blind? ) Yugi was born blind and deaf. So that makes him an easy target to bully. ( *rolls eyes at self* ). But since he can't hear he can't hear what they say. But his sisters help him. They helped him learn sign language. But what happens if a new student named Yami Sennen comes, and starts to bully Yugi because he thought he was rude. ( That's dumb ). And Yami joins Yugi's bully group. But what happens if Yami finds out that Yugi is deaf and blind.
