Natural ~Mi mo Kokoro mo~
Natural ~Mi mo Kokoro mo~ (it can be translated as "Natural: Both My Body and Soul" in English) is a H-game about a teacher on a forbidden relationship with his ex-girlfriend's little sister, that is also his student.
The protagonist is a substitute art teacher on a all-girls school for the elite on Japan. He is on his last thirty days on the job and has no problem in doing his job right, despite the rebellious attitude of Hotori Kawada, one of the art club's members, and the odd presence of Yuwa Izumi, a student with the mannerism of a cat who asks him odd questions. He also keeps a good relationship with his fellow teachers, like PE teacher Takayuki Akagi and female teacher Itsuki Tagami.
His problems come from another direction: his ex-girlfriend's sister and swim club's member, Chitose Misawa. Years ago, he first met her when she was just a kid. Now grown up, Chitose reveals a sexual crush for her previous brother-in-law, something the protagonist accepts.
With her parents and sister mostly away from home, Chitose spends most of her time in the protagonist's house, with them keeping a sexual relationship. But is this the real way it should go, should he really romance her? And what if their affair is discovered, what will happen?
At his heart, Natural ~Mi mo Kokoro mo~ is a Simulation Game: the protagonist must choose how to spend his time to walk through the game's multiple storylines and finally endings, based on the parameters affected by that time management and dialogue options.
