Kaby no Tsuma

Kaby's wife is cheerful, affectionate, and usually seen close beside her husband. She frequently holds his arm and shares his concern over the strange job they have commissioned from Fairy Tail.

She is more cautious than Kaby when the mages leave to infiltrate Duke Everlue's estate, questioning whether security around the mansion may have increased.

Her limited dialogue shows her supporting Kaby rather than directing events herself, but she shares his emotional reaction once the truth hidden inside Daybreak is revealed.

No magic, combat training, weapon, or supernatural ability is established for Kaby's wife.

She is an ordinary civilian and plays no combat role during the Daybreak mission.

Her involvement centers on the emotional and family history surrounding the book rather than magical action.

Kaby's wife first meets Natsu, Lucy Heartfilia, and Happy when they arrive to discuss the request concerning Daybreak.

The couple temporarily use a friend's mansion to make themselves appear wealthy enough that a guild will take the job seriously. Their actual home is a much smaller wooden house in the forest near Shirotsume.

When Fairy Tail returns with the book intact, Kaby tries to destroy it himself. The enchantment on Daybreak prevents this, and Lucy discovers that its letters can rearrange to reveal another title.

The book becomes Dear Kaby, a hidden message written by Kaby's father, Zekua Melon. Kaby and his wife later read it together at their real home.

She later appears with Kaby among the spectators enjoying Fairy Tail's Fantasia parade.

Kaby Melon is her husband, whom she supports throughout the Daybreak mission.

Zekua Melon is her father-in-law and the author whose hidden message inside Daybreak is intended for Kaby.

Natsu Dragneel, Lucy Heartfilia, and Happy are the Fairy Tail members hired by the couple to recover and destroy Daybreak.
