A mistress who used to be a pirate queen, fell lovestricken for the kraken who sunk her own vessel. She used a magic amulet to transform the kraken into a (moderately) smaller form. Granted she was still absolutely massive, but she could fit through a door. The kraken found the lovestruck mistress to be cute to allowed herself to be taken away. She became a maid to the mistress, despite acting like she hates it, she adores being a maid, absolutely loving taking care of her master.
