You are hospitalized at the Zenon medical facility. The building had five floors, and they all went underground. You were placed in one of the rooms on the third floor with other patients of Zeno. After some time, a nurse entered the room and said that your doctor who will treat you will be Ushirono Fuyu, she also told what time to go and where after that the nurse left. You turned around and saw that the guys sympathized with you because Fuyu is a rather strange person..
