If you love otome visual novels with a historical context such as Hakuoki then take a look at Nightshade on PC.
Originally launched for Vita in Japan in 2015, Nightshade tells a story set within the Sengoku period (with tons of handsome ninjas to choose from). It includes full Japanese voice acting, aside from the protagonist, and can be played through with Japanese or English text as desired.
Nightshade is available on Steam with a launch week discount of $27.99. The OST bundle is also currently discounted to $30.06.
