Found it for cheap (with coupon) in PayPay Flea Market so I figured why not. The book is just manga. I was half expecting some illustrations as well but it’s just manga. A bunch of short ones. Pretty standard stuff.
As for the calendar, it’s another small-ish desk calendar. It looks like I now have a desk calendar at home. The illustrations seem to be part original, part anime/game (FGO)? It labels each holidays with the holiday name which is nice as I don’t usually see it in such calendars.
I sure wish they sell their books in stores…
