'Our organization can't lose Marin!' Long Hair was at his wit's end.
'She is an important asset in the Dark-Bladed Shadows. Without her, the majority of our people will leave the organization!'
...
Marin's beauty alone was able to attract hormonal young men to join. They worship her as they went through the hardship of training. As a result, we name her as the Goddess!
I, Long Hair, one of the most enduring martial artists in the organization was chosen to the one who will take charge of Marin.
Due to my great endurance, I am able to trick her into thinking that I'm only taking easy on her. But at the end of our every match, I feel like I'm about to die!
However, I still need to act as if I didn't sustain any damage and that I held back.
This is all worth it. Marin herself is a phenomenal mortal who can do what she sees at first sight. If I show her my every move, I wouldn't be able to act my way out once she beat my ass.
