Secretary Saejima Yuka (Ano), a young man working part-time, a five-year-old kindergarten child, and a dying grandmother, Muto Taizan (Endo Kenichi) quickly switches between these various roles.At the same time, the cabinet support rate fluctuates like a roller coaster, and Nitta Ri (Keiya Yamauchi) is gradually approaching the truth about soul exchange!A sterilizer is placed in the living circle of those who have been converted...

And 14-year-old middle school student Hagiwara Akiho (Kurokawa Sōya) walked out of the private room of the Internet cafe where the same sterilizer was placed, and came to Shinjuku early in the morning.He asked the young people gathered on the busy street about the whereabouts of a girl named “Xiaoxue”. When he found a person who looked like “Xiaoxue”, he suddenly felt a headache!

On the other hand, Tarzan was threatened with a deal by opposition lawmaker Jinguji using the Budget Committee as a bargaining chip, but he did not accept it.At this moment, Taishan, who had a headache, suddenly found that he had exchanged bodies with Akiho!

After this exchange, Nekota Mamoru (Yamatoki Satoma) quickly confirmed Tarzan's identity (Akiho's face).After meeting Akiho (the face of Tarzan) at the Countermeasures Headquarters, he asked him to attend the budget committee on his behalf, but Akiho refused to cooperate and shouted: “The country can do anything!I'm going to find Xiaoxue!”In desperation, Akiho (the face of Tarzan) was sent to the Budget Committee, and the real Tarzan (the face of Akiubo) came to Shinjuku to look for Koyuki instead of Akiho.Facing the unfamiliar Japanese used by modern young people, Taishan felt at a loss, and what he saw in front of him shocked him even more!

In addition, Tarzan, who discovers numerous scars on Akiho's body, begins to understand the problems he faces...?
