Fei Fei

Fei Fei is Cai’s Named Golden Slime and Eiko’s frequent companion. Born with treasure-oriented abilities, she grows from a sleepy hatchling perched on Cai’s head into an active bomb-maker and, after the war, a childlike human-form flower girl within Lux’s extended family. (Chapters 372, 690, 1232)

Biography

Heaven’s Gate and the continental wars

Cai hatches Fei Fei from a chosen egg in Leaf Village and immediately interprets the rare Golden Slime as a sign of future wealth. Fei Fei’s own response is less mercenary: newborn and sleepy, she wakes for the promise of treasure but quickly dozes off again. Traveling with Cai brings her into Heaven’s Gate’s campaigns, where she remains close to her master during battlefield planning and fearlessly tries to free Cai when Rose binds her. (Chapters 372, 440, 481, 529)

Her loyalty develops alongside friendship with Eiko. Rather than remaining a passive mascot, Fei Fei learns to help produce Blast Bombs for war preparations and accompanies Cai when the coalition moves toward larger conflicts. Her small body limits direct confrontation with high-ranked opponents, but crafting explosives lets her contribute at a scale unavailable to an ordinary E-Rated hatchling. (Chapters 657, 690)

Open Heaven’s Gate

After the war, Fei Fei’s place in the family becomes more domestic but no less mischievous. She eats cake with Eiko, goes fishing with Lux’s in-laws, helps light the ceremonial cauldron, and participates in the obstacle race from the Bifrost Bridge. These choices show a childhood secured by the victory: the same appetite for excitement once directed toward bombs now animates games, meals, and collective celebrations. (Chapters 1224, 1226, 1230, 1231)

Fei Fei ultimately gains the ability to assume the form of a young girl. Wearing a yellow dress, she serves with Eiko as a flower girl and carries the box containing Lux’s wedding rings, then joins the later group wedding procession. Her transformation and ceremonial role mark her latest development from Cai’s rare pet into a recognized child of the wider household. (Chapters 1232, 1234)

Appearance and personality

Fei Fei begins as a small golden Baby Slime who usually rides on Cai’s head. She speaks in short sounds such as “Wae” and “Da Wae,” sleeps readily, and becomes animated by treasure, food, play, or Cai’s danger. In human form she appears as an adorable young girl associated with yellow clothing and eyes, retaining the cheerful, impulsive behavior she shares with Eiko. (Chapters 372, 529, 1224, 1232)

Abilities and skills

At birth Fei Fei is an E-Rated Golden Slime with Treasure Hunter [EX], Dig, Payday, Golden Body, and the Golden Girl title. Payday fires a coin for fixed physical damage and steals between one and one hundred coins if the target carries money. Golden Body grants immunity to status ailments, while Golden Girl doubles experience gained from Beast Cores. These gifts favor discovery, growth, and opportunistic attacks rather than sustained front-line combat. (Chapter 372)

Fei Fei later makes Blast Bombs with Eiko and can spit a fireball, expanding her usefulness into explosive support. Her latest transformation into a human form indicates substantial growth, but the corpus does not provide a revised stat sheet or prove that the transformation removes her original rating-based limits; stronger contributions are normally collaborative and prepared in advance. (Chapters 690, 1226, 1232)
