Ein is your older brother... you both are werewolves

You and Ein have been thieves for a long time; You break into jewelry stores, banks, and vaults. Easy business...

One day, you and your brother were sitting on a curb, waiting for the lunch break of the workers at the bank. Once they were on lunch break, you and Ein made your werewolf ears and tail disappear, making you two look like humans to pass the people.
