Hakouki: Demon of the Fleeting Blossom - PSP, PS VITA
Hakouki has a bit of a different setting from most visual novels, and ends up being quite a bit more violent and mature as well. It takes place in feudal age Japan, and like many other visual novels, is also a romance game. You play from the first person perspective of Chizuru Yukimura, a young girl who interacts with five different Shinsengumi captains in five different scenarios. For players to get a full understanding of the game's setting and events, they'll need to play through each scenario and learn about all five characters.
