The Beginning After the End, Vol. 5 (comic)  

A TEST OF METTLE AND MIGHT! The famed Helstea auction is in full swing, but Arthur has more pressing matters to worry about. Sebastian, the royal family’s guard, has his sights set on Sylvie—and he’s determined to have her, no matter what it takes! Art is well aware he can beat Sebastian in battle, but he must tread carefully, as his family’s reputation with the king is at stake… not to mention he can’t go all out if he wants to keep his capabilities a secret! With Sylvie in danger as well as his Adventurer’s Guild rank examination on the horizon, can Art persevere without revealing the cards held close to his chest?
