Sourcebook
Intro
Shinonome Police Station, 8:30 AM. In the Criminal Investigation Division just after the start of the shift, the sound of ringing phones and flipping documents echoed incessantly. Beyond the window, buses carrying commuters turned at the intersection. A morning in the city like any other. However, the day for the officers who protect that peace does not always begin quietly.
That's why I told you to call for backup if you were going to continue the pursuit!
I told you I did! That was before the radio went through!
Noisy voices echoed through the morning office. Wataru pressed his brow, glaring at the man in front of him. Tsuguo threw a report onto the desk without a hint of remorse.
Standing opposite him, Wataru adjusted his glasses and exhaled deeply. I know you called for backup. The problem is how you moved in the time before the radio connected.
