An adventure game in which you become the main character, Ryuichi Hihara, and fight monsters called yokai. The story is based on an ancient "agreement" that separates the worlds in which humans and demons live with "doors" to avoid useless conflicts as much as possible.
The pact was signed once every 200 years by those who inherited the bloodline of humans and demons, and was continuously kept. And now, once again, the time to conclude a pact was approaching...

Five heroines appear, and the "attack attribute" and "five elements attribute" differ depending on the character. At the end of the day, you can talk to the characters and deepen their relationship.
