On the Trail of a Liar (S01E05)

The Ghost Detective Club takes on an intriguing new case from a professor who showcases artificial animals at his Neo Animal Museum using Deco overlays. He’s particularly proud of his creation, the Nue, but its appearance differs significantly from what’s depicted on Decopeedia. Seeking clarity, he enlists the detective club's help. When they see the professor's Nue, it appears far from the adorable creature shown on the Decopedia entry. Despite this, the professor remains adamant that his version of the Nue is the authentic one.
