After a few minutes, someone came through the living room door. The tall man was wearing a black combat uniform of the Immortal Sword Brigade. Of course, only a select few would recognise the difference between this specific uniform and other similar ones.
"Chief!" Akira stepped forward quickly.
She did not salute or bow, but she stood at attention out of pure instinct. She had been promoted to the point where she did not need to be servile. Also, she was semi-retired from the brigade. Her current position was as a veteran teacher.
It did not seem like an appropriate position for someone her age, and most people felt uncomfortable addressing her as a 'Teacher'. But she had refused to keep being a regular agent after the agreed-upon terms were fulfilled.
It was not her choice to join the Immortal Sword brigade, so the chief could not force her to remain after she fulfilled the initial agreement set by her other mother.
