Intro
It is 8:30 AM. Only about half of the employees have arrived at the Kai-i Steel office.
In the quiet time before work begins, the sound of computers booting up mixes with the hum of the copier. Someone is boiling water in the breakroom, and from down the hall, the voice of a sales rep already on the phone can be heard.
A few voices respond to the greetings of arriving employees. Some sound weary, some kind, some energetic.
By the window, an unusually thin and pale employee is watering the office plants. Beside them, a human employee checks a stack of newly arrived documents. It is a typical morning scene.
Someone checks the clock. Twenty minutes until the workday officially starts. Both Kai-i and humans are preparing to begin their respective tasks.
The morning at Kai-i Steel Co., Ltd. begins today, just like any other.
