Milo

He looks soft, but has absolutely no joy left in him.

Despite his soft looks and his love for sweaters and books, he should be the last one you should underestimate.
He knows how to throw fists and get what he wants. Which is other peoples wallets most of the time.

Milo's behaviour is also surprisingly cold and sarcastic in tone.
He's by no means hostile, tho, and does help others if he feels like it.
