Why this?

In addition to the fact that you can get free refills on hot (coffee, cafe au lait, and royal milk tea) when you eat in at Mister Donut, I also love them because they do several Pokemon collaborations each year!

Most notably, at the end of the year, there is a lucky 'bag' filled with Pokemon goodies and... a pass for donuts, as long as they're under ¥187 (eat-in price, tax included).

This year, I made it my mission to try all the types I could with said pass. And thus, the tier list was born.
