The last two chapters of Saki Biyori, the second one in color!
It was fun but now it's over 😢. Saki Biyori lasted for roughly 100 chapters (counting the ones from YG) and was published for almost 7 years, quite a long time for a spin-off gag manga.
I can think of quite a few totally hilarious chapters but one of the most memorable things that came out of this manga (at least for me) is Koromo's birthday song (short version) ~Koro tan yay~. I will always remember that.
Biyori 75-76 (Mediafire)
