Kotoko is asked why a suspect had thrown a dead body into the Guardian’s swamp and she starts constructing a story. This ends up being a rather tragic tale about Tanio Aoi filled with love and regret that the Guardian is also shocked to hear. Two years later, random acts of violence were happening in Makurazaka City. The suspect seems to be the ghost of the former idol, Nanase Karin…

Kotoko arrived in Makurazaka City to take care of the incidents with Steel Lady Nanase and happens to run into Saki, who had become a police officer. Saki decides to research Nanase Karin a bit more and learns that the former idol had died a mysterious death. In order to defeat Steel Lady Nanase, they would need more details, but…

Kotoko realizes that Steel Lady Nanase is a spectre that was born from her own wiki site. In order to defeat Steel Lady Nanase, who is made up of people’s imaginations, she has to come up with a story that’s more interesting than Steel Lady Nanase’s. Kotoko ends up asking Saki for help to defeat Steel Lady Nanase. She then meets up with a ghost that is at the site where Nanase Karin died, who also happened to see her die...

Everything is finally in place, and the committee to conquer Steel Lady Nanase is now in session. Does Steel Lady Nanase actually exist? Perhaps she’s just a made up urban legend. A battle between the truth and lies begins to figure out her existence. Kotoko gets on her PC and starts posting her own deductions...

Just as it looked like the site readers accepted Kotoko’s solution, it ends up getting shot down. However, Kotoko had another solution ready. In order to defeat Steel Lady Nanase, she unleashes a second and third solution, but Sakuragawa Rikka and Steel Lady Nanase continue to get in her way. Will they be able to vanquish the ghost?

Kotoko came up with three solutions, but they all got shot down. Kuro keeps trying to grasp the future where they can defeat Steel Lady Nanase, but Rikka made it disappear once again. But Kotoko wasn’t done yet. Steel Lady Nanase is not a ghost. What is Kotoko’s 4th solution that may finally put an end to Steel Lady Nanase’s existence once and for all?
