Overall Rating 4/5 Definitely a show worth watching and owning. Set in Feudal Japan the lead character, Yukiatsu Ryuudou, eventually joins a secret sub-government agency to fight with the power of Ayagami (to form weapons from true names). Yukiatsu, age 39, is overall joined to a group of other oddly talented adults and a couple of teenagers. So if you want to watch a show that isn't about another Japanese high school, this is a good show to get started on. The group fights Youi (aka Ayakashi, Yokai, supernatural creatures from folklore). The group travels around protecting towns and whatnot while the main plotrevolves around government change and the agency's ongoing usefulness.

Theme Songs 4/5
Two opening and two ending themes are all solid and interesting. All fairly fast paced and good, I never skipped them.

Ending 4/5 (conditional)
The TV ending finished the plot well enough.
The OVA has a more complete ending but a less happy ending, thus 3/5.
