Testuya recently had been seeing the same mysterious dream, with a lonely kimono-clad girl gazing at the moon in the middle of an open grassy field. He returned to his hometown of Koga after four years in Tokyo and was a bit saddened to see his place of memories changed due to recent development. One night, he headed to his favourite place, the garden of irises Ayame-en, and was startled to find a girl there who looked like the girl in his dreams. He joined the archaeology research group that she was a part of with the intention of getting to know her. Contrary to his initial impression, Ayame was a hardcore gamer, lacked common sense and called herself a princess from the Sengoku era. [From Hau~ Omochikaeri!]
