Sengoku Collection
戦国コレクション (original)
Sengoku Collection revolves around many samurai who are accidentally removed from a parallel universe inhabited by well-known historic characters. Unlike the historical war period known to us, all inhabitants in this unique world look like high school girls. Coming from the medieval era and finding themselves totally amazed by everything they encounter in modern day Tokyo, the girls become best friends through their adventures.
