Faye, a crew member on the dragon-hunting airship Quin Zaza, shares an unbreakable bond with Soraya, forged in childhood poverty. Together they labored as shoe shiners in a harsh urban environment, surviving through their partnership. During those difficult years, Soraya occasionally bought books for Faye, the only literate one, investing in a better future. One book remains Faye's treasured keepsake. This deep connection led them to join the Quin Zaza together, with Faye explicitly signing on because of Soraya. Their commitment is absolute; they intend to remain together even if the Quin Zaza disbands.
