Japan in the second half of the twenty-first century. There was this urban legend. A place called the Yukioka Research Institute, located in Gikkoucho, Anraku City, Tokyo. It is said that if you undergo a remodeling operation by a mad scientist there, you will gain power in the supernatural realm. However, in return for gaining power, it is necessary to become a mad scientist\'s test subject, so there is the risk of failing and losing one\'s life, or being turned into a monster. Those who need power clinging to straws, those who simply admire supernatural powers and want to peek into a new world out of curiosity. It just so happens that a suicidal person is in a desperate state--with various thoughts hidden in their hearts, test bench applicants visit Yukioka Research Institute today as well.
