The Kawaiifier is an technological device that appears in Kuu Kuu Harajuku.
The Kawaiifier is one of Love's inventions. It is used to "kawaii-ify" objects by performing a spectral analysis of the subject, isolating all desirable kawaii vibrations and uses that data to externally amplify and expound those oscillations.
In Feline Finest, Love has created a portable version of the Kawaiifier, but as it's incredibly unstable, it requires delicate and skilled handling to operate properly. When Rudie attempts to use it with lack of either trait, he overloads the Portable Kawaiifier and it starts zapping everything in range, changing outfits, mutating Twisty T's cat and himself, plus turning the Tour Van's tyres into fluffy throw pillows.
