While on the trail of a group of smugglers who are transporting a dangerous weapon known as the Ryunka, Space Federation Officer Birdy Cephon Altera travels to Earth and disguises herself as the model/actress Shion Arita. While fighting one of the smugglers however, Birdy accidently kills schoolboy Tsutomu Senkawa and the only way to preserve his life is to transfer his consciousness to her body while her superiors reconstruct his body. Now sharing the same body, Birdy and Tsuotmu must find the Ryunka before it can destroy the world.
This four-disc set of the 'Birdy the Mighty: Decode' anime contains all the episodes of the series. The first thirteen episodes of the set cover the series' first season that sees Birdy hunting for the Ryunka while Tsuotmu must learn how to deal with how shearing a body with an extra-terrestrial police officer affects his school and social life. These episodes are good with some nice focus on Tsuotmu and have an interesting plot.
The next twelve episodes of cover the second season of the show were a some of the aliens responsible for the Ryunka incident go into hiding on Earth and Birdy must find and arrest. This second season is probably my favourite part of the series as it reveals some nice information on Birdy's past when she meets an alien refugee on Earth who was a childhood friend.
The final episode of this set is an extra episode set between the two seasons that is reasonably entertaining.
'Birdy the Mighty: Decode' is a very entertaining series with a nice mixture of humour and action, and also has some reasonably good emotional moments as well. The English dub for the series is generally good and while the animation does have some issues that some people could dislike, I found that it suited the series relatively well. The plot of the two seasons is interesting enough to keep me watching while some of the characters could have done with a little more development, the major cast were done well.
Overall I greatly enjoyed this series and would give it a high four and a half stars.
