Sadly I quickly found out that the gags/jokes from previous stuff, carried over to this one, I think that is a shame. They could have easily made these characters more mature, more adult, yet they went for their high school personas, which is a real shame.
There are various new characters, and at times I was just confused as to who was who, but that soon fades and I started liking those characters more than I did the K-on characters.
It was interesting however to see them in college, see them struggle with all the new things and make new friends.
I am glad though that this one is a one volume, and not more. Since I don’t think I would want to read more about this.
