Shosuke (Hirano Nari) is a patient in the clinic of his father Matsuan (Tamaki Hiroshi). He comes to the clinic for help and tells Matsuan and Aichi (Aoi Wakana) that they always feel that their dead sister Akyo is alive in their bodies.
In order to solve the mystery, Ashi moved to Zhuangzhu's house.Shinkichi (Asuka Kudo), a decoration craftsman who works at Shosuke's house, is considered to be related to the Nighthawk murder case that caused a commotion.Aichi and Sengoro (Masahiro Takashima) believed that Shosuke's incident was also related to this, so they began to look for Xiaofang (Moeka Honoshi) who held the key to the incident.
