Beside one of the distributaries of the great Lorls river, laid a young lady and a young man. They were Sato and the black-haired noble, Layla Arnhaunt.
After confirming her identity, Sato had decided to save the young lady's life as he felt that she was the key to understanding the entire plot hidden away from him, which also included the reason why Cecilia was so desperate to kill him. Since he found a possible source for his answers, Sato would not let it go no matter what.
In order to avoid an awkward moment, Sato didn't undress Layla but cut off the piece of clothing that covered her injury. Once he did so, Sato then removed the dressing that protected it from infections. He was then greeted with the sight of a grievous cut that ran horizontally through her abdomen, just a bit above Layla's belly button.
