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)

this anime will have you craving more with each episode like the first part. if you're into alien women who fight crime on the galatic scale with killer quick acrobatic moves that bewilder her enemies into submission then you'll love this anime by a long shot. full of humor, adventure, action, mystery, crime fighting, outerworldly powers and creatures, and romance. i absolutely loved this anime and it's first part. the characters and story are very easy to fall in love with. the relationship between birdy (the alien warrior) and senkawa tsutomu is the best. shion aka birdy is so full of energy and joy that nothing seems to keep her down even as past relationships come to haunt her. who wouldn't love an anime with an alien women teaming up with a human man to save the world.
