I will miss Yotsuba. I loved her antics in Volume 9,10,11 and this one. She keeps getting funnier and more interesting. Loved that she painted her dads table all blue and how he punished her for spreading paint everywhere. Also the camping trip was fantastic, and so I could go on with the things that happen that were fun. I can just say, I had a great time reading this.
However one thing I would like to see, more clothes for Yotsuba. She always has the same pants (short or long, depending on season) and shirt (short or long, again seasonal). I know she has other clothes too, and I would like to see some variety in what she wears.
Other than that, Yanda must still be deleted from the face of the earth. God he stays annoying and mean. :\
Well I will be (im)patiently waiting for the next volume.
