Adelle is secretive and somewhat defensive about this and hides her insecurity. She is disturbed when she realizes she is getting comfortable in Clan Gully and leaves, but the friendship offered by Luso and the rest of the clan helps her to open up and gain a better outlook on how to live.

Adelle first appeared to Clan Gully to vanquish the Deadly Nightshades and an Alraune. She offers her services and requests a split of the earnings between herself and the clan. However, at the end of the quest, Adelle takes off with the Alraune Drill from the Alraune, a loot that Cid had wanted, as it fetches a high price in the market.

She reappears attempting to steal the mark Clan Gully had hunted earlier. She unknowingly stepsinto a trap Cid had laid out, and is interrogated. She reveals selling the Alraune Drill and spending the gil she earned. Clan Gully abandons her and arrives at the pub to find her waiting, much to their surprise. She forces her way into the clan.

During the meeting with Lezaford, the high mage hints on Adelle's secret. Adelle shrugs it off but later gives Lezaford a visit; he tells her she must accept her gifts or run from herself forever. When Adelle realizes the mage cannot give her a solution she leaves, and decides it is time to stop using Clan Gully. She leaves the clan, taking most of the money in their stash. Enraged, Luso and Cid go on a quest to pay for their to-be-huge meal
