Chapter 984 - Kit Kat Paradox

To create a Kit Kat, you need to already have a Kit Kat. The fillings of the Kit Kat wafers is actually composed of crushed Kit Kats.

Thus you'll theoretically have Kit Kats with different levels of purity based on their generation. A generation one Kit Kat would thus be incomparable with one from ten generations later. Of course, at some point all later generations will appear identical.
