またまたillust/4890237 の続き。電車がダメで携帯もダメなので、姉が公衆電話で連絡を取る間、情報モニターの前で待っている妹。あっという間に不通区間が広がっていく。

Another continuation from post #4890237. The trains are out, and so are their cellphones, so while the older sister tries a public phone, the younger sister waits in front of an information monitor at the station.
In the blink of an eye the out-of-service area on the train map expands.
