The old Karas is dead, killed by an evil ex-Karas who now named himself Ekou. He started a series of murders against humanity by making his loyal youkai drain the body fluids from humans.
Otoha, a young man who just woke from a coma, is chosen to be the new Karas. Him and his trainer, Yurine, start the fight against the evil forces of darkness that are triyng to conquer the city of Shijuku.
Although is six episodes in length the quality of the animation is outstanding in my personal opinion, that's why I made a few vids out of this series. Storyline-wise is not bad at all, I found it to be verey appealing from the very start, a very dinamic animated series, indeed.
