The Mysterious Master
William wasn't a saint, but he got his time occupied with tons of things actually. Not to mention most of the girls here were still young, except for Ro who were considered a young lady now.
He always dealt with Ro in caution. After all, she loved to play tricks on him, even when the two sat together, laughed and talked about different things and old times.
"What? Don't tell me keeping track of your training is bad!" William rolled his eyes when he saw Ro. But everyone else seemed to share with her the same opinion about William's harsh methods.
The way William tested them was simple, and brutal. He'd spar with them one on one, with things ending up quite bad for them each and every single time.
No matter how they tried, no one was able to even keep up with William, especially when William kept growing stronger.
They all trained starting from the end of the big war. And yet, when they compared themselves with William, all they could think about was how monstrous William was.
