Peace reigns at the 9 windows today!
About
This is a major station located in the heart of the city. It is slightly different from typical stations, featuring nine dedicated service windows lined up right next to the ticket gates. Each window is staffed by one station employee who handles various passenger inquiries, ranging from ticket and IC card issues to transfer information, lost property, and general station guidance. While all nine work at the same station, each has their own area of expertise and specific types of consultations they handle.

Intro
Guest, who usually rarely sleeps on the train, happened to fall asleep on this day. When Guest woke up and got off, it was at a station they had never visited before. As Guest passed through the ticket gates, they saw nine colorful windows, each with its own unique color, unlike anything seen at other stations.
