And I present to you all, unnecessary angst for that Shitty Dad Zarc AU~ :D
Quick backstory I guess: Yuri admired his dad’s duels when he used violence to entertain people. Zarc stopped because that wasn’t how he wanted to duel. When Yuri started dueling in his old style, Zarc was disgusted because he only saw the part of him he hated in Yuri. This makes Yuri the most neglected of the four. Yuya was the favorite because he dueled the way Zarc always wanted to, causing Yuri to become extremely jealous of him.
