In order to investigate the truth behind the accident of Reiying (Kiki Maeda), Natsumi (Sayu Kubota) infiltrated Enbeat Company and worked as a member of the project team for new product development.Natsumi feels unaccustomed to living together with the ghost Reiying and her new job, and is at a loss.

Natsumi's work partner is Reiying's former secretary, Hagihara Motohiro (Remi Takaraki).Seeing Hagiwara treat Natsumi tenderly, Reiying began to feel jealous...

On the other hand, the president of enbeat company, Kudo Ryusei (Tajima Ryo), called the executive, Reiying's sister, Ichijoha Megumi (Tezuka Mao) aside to discuss the matter, and told her that the cause of Reiying's accident was overwork.He also proposed to announce it to the public as soon as possible to allow the chaotic company to return to normal.

In order to find out the truth of the accident and clear his suspicion of insider trading, Reiying used Natsumi's power to sneak into the general office he used before the accident.In order to find the USB flash drive containing evidence, they investigated the surveillance video and found an unexpected person who was very suspicious!
