Since I followed episode 1 to episode 13, I never got bored. The story is so interesting that it makes me curious like a roller coaster. Dark. Emotions. Everything is combined well. Every fight that shows up can make me hype. I really like fights that are full of gore. What I like the most is when Higan-san uses ninpo or ougi. (I forgot what it's called). It gives me goosebump. Even though in the end it uses the mecha concept, I don't feel bored. Because I feel that it has become a distinctive feature in this anime. (Besides, I still listen to the songs Vengeance and Legend begin.) Eventhough it was complete, I felt very satisfied. Moreover, because I get a lot of inspiration as a writer.
