A promising beginning led to an expected outcome. This is how I would summarize the second season in one sentence, and that is because of the same characters some of us love and watch dearly find themselves faced with another threat undergoing all sorts of labors in order to emerge victorious.
Every action we take has consequences and you can see that in this series very well because of the famous samurai in japan's history like Miyamoto Musashi and Sasaki Kojirō that were revived because of some spirits that hateful of the course the history had taken and decided to change it themselves.
The end is pretty much the same as the first season with the two main protagonists on their way to save the day and restore the peace to "Great Japan" as Tokugawa Yoshihiko refers to the country. The expected outcome is what lowers my score for this series because it's not very entertaining to know the results before you even finish watching it.
Artwork is virtually the same because this season focused more on fan service rather than improving the storyline but maybe I'm expecting too much from a series that as ecchi and comedy.
So if you enjoy comedy/ecchi anime that have a drop of drama then the Hyakka Ryouran series is waiting for you. Thanks for granting me some time for reading this review... I hope it is helpful
