Like its predecessor, this book offered no contributions to my schema, but I really don't care. I had a wonderful time and enjoyed reading all the fun little stories, and that's that.
In particular, I really liked the story about Mechamaru. Not only did it expand upon his character a bit more, but it was quite interesting, and maybe a little bit sad.
I actually now in general feel much sadder about what happens to all of these characters in the main series. But at the same time, this was a nice balm.
