Meitantei Conan: Zero no Tea Time is a series of 6 short episodes (13 minutes each) about Amuro/Zero's life when Conan//Shinichi isn't involved. The visuals are a bit inconsistent and the soundtrack is very similar to the main series'. The voice acting is pretty solid. There isn't a plot to this short series. Take this as "fanservice" for the fans of Amuro/Zero. If you really enjoy him as a character, you'll enjoy this a lot. If you're like me, meaning that I only enjoy Meitantei Conan because of the story surrounding the black organization, you'll find this pretty boring. It's a 4/10 for me.
