Hyakka Hyakurou: Sengoku Ninpoujou (English)

If your into historical otome setting's like Hakuouki then this is your game. The plot is dark and well written. I spent around 40 hours playing all the LI routes and reading the extra stories. I highly enjoyed this game, the plot, and LI's.

Nightshade is one of the best mature otomes out there. It has a compelling and strong heroine, interesting love interests and a quick-paced story that will make replaying the game to get all routes a blast.
This game might be on the pricier side, but it's a must have for all fans of the genre.
