Adult action-adventure game released by Illusion software.

Here was an isolated mountain village named Monobeno. The village here had a certain rustic charm and kept faith with the coexistence of humans and monsters. Our story began here.
The protagonist, Tooru Sawai, was born and grew up here. He and his sister, Natsuha Sawai, depended on each other. While she had lost some of her memories by accident…
It had been a few years since Tooru Sawai moved away, he set foot again in this beautiful and magical land full of adventures and legends.
Apart from the age-old Tang Umbrella Monster Hisyakaku, he was reunited with two young girls: his childhood sweetheart, Alice Arisma, and Red Bear Monster, Sumi.
When there was a mask dancing at the summer festival, Natsuha Sawai fell down and suddenly grew up. Only through one night long, her body turned to an adult size. She was tortured by this abnormal growing, both physically and mentally.
It was caused by disease or monsters’ haunting?
Between medicine and legends, Tooru Sawai tried to find a way to save his sister. With the help of Alice or Sumi’s power, what kind of romantic story would happen during their adventures? And was there something happened more than brother and sister?
This was a story about humans and monsters, diseases and monsters’ haunting, and the past and the future.
