This is a late adaptation of a really old story (1985) that was droup out...
It's a a really interesting anime, with a lot of action&fighting!
The science-fiction theme is really indulge in this anime, with makes the fighting parts really cool, and captive to the eye :p
There's also some comedy, but really low, with is a bit sad, since the theme (2minds in 1 body), could make a lot of "gags" xD
But this is a very interesting story nonetheless...and you'll certainly enjoy it!

There's also a set of 4 OVA, that tells a similar story, with the same characters, but in others circunstances...so if you liked watching Tetsuwan Birdy Decode 1&2, look for those OVA's too ;) (show less)
