The Familia was first formed through Dia's help after a misunderstanding between the player and Emma. Looking to expand their Familia, the members recruited Iris, who admired adventurers and needed a way to pay off her debts. Later on, they attempted to recruit Oriana due to Gita's suggestion; however, she refused their offer, stating that they weren't as strong as she would like a potential conversion Familia to be.
Despite this, she agreed to become the Familia's personal instructor after Emma helped save a lost child she was looking for. She ultimately decided to join after she was reminded of her past when Emma used herself as a decoy in an attempt to help them escape a Killer Ant Pass Parade.
