At 13 episodes, SoulTaker is a short series and benefits from excellent animation quality. The series is very cryptic up until the last few episodes and why many will end up confused after the first 2 volumes, I enjoyed them all. The characters are all fun and interesting and while this isn't the best anime series around, give it a try, its got that goth/horror/sci-fi elements mixed with the classic styled transformed-superhero action popular in the 80's.
