This OVA works as a comical side story. You still have to watch the first Black Butler series in order to understand it.
There is just a simple story. As a charity action, the Funtom company group decided to perform a play for orphans: Hamlet. But the Phantomhive lead didn't preview that he'll have to play in it.
The animation is the same than the series one. No point to add.
The sound is the same, with the same voice actors. I appreciated their funny side.
The characters shine here. They just doen't make sense and it is quite plain hilarious. You'll have the opportunity to see the cast reunited on one same scene from Ciel to Prince Soma passing through Ran Mao and Viscount Druitt and William T.Spears.
Overall, this little OVA doesn't stand much on his own but is it quite an entertainement if you enjoyed the series and it's cranky characters. It definetely respect the vibe of the animated series.
Score: 3.5/5. If you enjoyed the series, try this one out.
Next! Tales of the Abyss and Darker than Black
