Some imported KitKats for my D&D group (if you're reading this, act surprised!). In our current campaign, we can truly need all the luck we can get.
There have been over 300 seasonal Kit Kat varieties in Japan since 2000, including adzuki, green tea, and soy sauce flavor. Kit Kat is, somewhat surprisingly, one of the best-selling confections in Japan, probably also due to the fact that the coincidental cognate Kitto Kattsu (きっと勝つ), which translated to "You will surely win!" made it a popular choice as a good luck charm!
