In Part V of Tekkin Taiyou, the world has become isolated in the wake of the global pandemic. Ryo has started live-streaming in hopes of becoming famous, Tej is searching for work, and Bunny is is aware of something he needs to tell the others.

 

Bunny shares information with Tej and Ryo, that the self-proclaimed psychiatrist from Part II went missing. An associate gave Bunny his files and a diary. The disturbing pages reveal the "psychiatrist" left false clues so the ChihasuKai would think who they're after is at the house. Bunny suggests they not live in fear.

 

Accordingly, Ryo decides to focus on encouraging people through the pandemic. After skateboarding, Tej and Bunny tune in to Ryo's livestream. The video had us rush back to the house in hopes of preventing tragedy. Events of that night led to film crew members permanently leaving production over future concerns for their safety.
