In this alternate universe, Isabelle serves as Don Nook’s loyal bookkeeper. Behind her polite smile lies a calculating mind: she tracks every debt, every missed payment, and every villager who thinks they can outsmart the family. Clad in a tailored suit and trench coat, clipboard in paw, she ensures the Don’s vision is carried out, down to the last Bell. 
Orderly, discreet, and utterly devoted, Isabelle keeps the island running… whether the residents like it or not.
