"Welcome to the famous Thieves School! In this place, you'll learn everything related to theft and you'll able to graduate in Stealing Arts". Those were the first words that Mist and Courage heard when joining first year of this University. However, after almost 5 years of study, these students failed a key exam, leaving them with no possibilities of graduating. The professors decided to give them one more chance, an special exam consisting in a delictive tour around the world, in which they'll face many dangerous situations while stealing valuable goods.
