KUROMUKURO is a superbly illustrated animation, with beautiful colors, well-drawn characters who look fairly real, interesting backdrops, and then plenty of action between good guy & bad guy characters and their mechas. The storyline is interesting and gripping as far as stories go for this type of anime, not being terribly deep but also not being flighty or silly as many of these things are. The main characters are pretty well done, not only physically but psychologically, and you can actually have some empathy for them as the story moves along through its two seasons. The bad guys are aliens come to Earth and they are, well, bad! It becomes the job of the local science agencies and military to fight them off and find a way to defeat them permanently. The two main characters, cute little Yukina, and the handsome Samurai warrior brought back from 450 years ago, Ken, do a good job of fighting through a complex relationship and a host of difficulties. Altogether a well done story and anime and surely one of the better ones that is definitely worth watching.
