Yuusuke was sent by his father to steal Momoko Kuzuryuu away from Jovi Edelweiss and he almost succeeds, only to be interfered by Jovi's rematch. They fight for several minutes with both sides taking heavy damage until Jovi used the technique Myriad Seal to take away all of Yuusuke's abilities. With his abilities gone, he could no longer fight, giving Koushi the win.
