Darien and Serena soon had to prove how strong their love was. Prince Diamond of The Nega Moon Family had fallen for Sailor Moon, but this obsession was soon defeated when The Wiseman betrayed The Nega Moon Family. He also tried to lie to her about her loved ones, but Sailor Moon didn't believe any of his lies about her loved ones especially Tuxedo Mask. Tuxedo Mask also called him on his lies and came for Sailor Moon when she needed him. He also fought Prince Diamond for Serena and had won.
