Senkou no Night Raid
This series was one that really grabbed both of our attention! Not only do you get a period, quasi-historical anime, but action and supernatural elements as you come to learn more about the 4 "gifted" members of the Sakurai spy organization and the events they help catalyst.
I'm really enjoying all the series the A-1 Studio is producing like Darker than Black, Occult Academy, and of course, Senkou.
Fav. characters: Aoi and Isao
