The Lemmings Incident
At the Materials Compiling Group No.3 headquarters Saki Aikawa was approached by Kōzaburō Arase who lifted his shirt to show the shoe imprint on his chest so that she could run the footprint. Aikawa thought he was joking, but did so at a glance and identified it as a woman's shoe and inquired what the story was until Fumiyo Yamada came with a first aid kit to tend to Arase's bruise.

Solitaire's Escape
While eating snacks at the station, she alerted Tsubaki Iwanome about a strange news report on TV alerting the public about Mystery Solitaire's escape despite the gag order imposed by the police. It turned out that the newscaster and report were being broadcasted on all airwaves by none other than Mystery Solitaire.

Later after Mystery Solitaire released zeppelins around Tokyo with a strange symbol to the public, Yamada informed Iwanome that he had been summoned by the Central Office at Sakuradamon Station.
