The 2 volumes are an excellent collection of one-shots!
The plot can seem a tad repetitive from time to time (ie, a couple stories with a similar plot involving the annoyance of Prince Soma), but overall each story is fresh and entertaining, not to mention funny!
Sebastian served as a babysitter. Grell tries on the Madam's clothes. Lizzie insists on Ciel only eating a "cute" scented curry.
Really, it's all very original.
As this is an anthology, the art changes with each story so I can't give much feedback on that. However, if you don't like a person's art, each story is only about 8 to
14 pages, so you wouldn't have to endure it for long. ;)
I say, if you can find it, give this a shot.
