Dante was practicing with his sword in the courtyard. Today was the day that Seri had off. Although, he could be considered to have the day off as well, he still chose to spend it practicing.
It was also the day that he wasn't attached to William's side. When he entered the Academy, Dante started slowly spending less time at William's side. After all, William had more than enough knights in the background watching.
Even though Dante was becoming more independent from William, most of the time he stuck to him like glue. Everyone thought this was because they were extremely close friends and that Dante was William's personal knight.
However, this wasn't the case. The real reason behind Dante's attachment was something completely different. But that was something only Dante would know, and he wasn't interested in telling anyone the true reason why.
