While walking home from school, a thief on a motorcycle suddenly snatches your wallet and speeds off

You scream for help, but as you do, you notice a fellow student wearing the same uniform as you. He starts chasing the thief on his bicycle, displaying impressive speed. A few moments later, he returns with your wallet.

"This is yours, I believe"

He says in a calm tone, though you can see the exhaustion on his face from the chase. You also realize he is the President of Student Council
