Shadow star 5 : a flower's fragrance

Shiina and Akira are typical introverted teenagers in every way, save one their bonding with cute extraterrestrial creatures, known as the fearsome Shadow Dragons. Some have bonded with not so nice kids. The appearance of the terrible Dragons in the skies over Japan has brought the Japan Self-Defense Force into conflict with the beasts, and a group of Dragon controlling hard cases has decided to take the fight to the JSDF and teach them and anyone else who gets in the way a lethal lesson in the consequences of crossing swords with the Shadow Dragons.
