The 3WA have been tracking a criminal boss but he hardly ever appears except to the winners of a worldwide beach volleyball tournament. Kei and Yuri are assigned to compete and win the tournament, but must undergo extremely rigorous training by one of the 3WA's crazy coaches.

Kei discovers that Yuri is hanging out with a young teenager, and goes over to them to give Yuri a slap on the back, but Yuri's head falls off! It turns out the boy had created a life-size android of his crush, Yuri! Oops! Kei apologizes, but the 3WA wants more than an apology. While the android is being repaired, Yuri is ordered to take the place of her look-alike. Yuri protests until she learns that the boy is part of an extremely wealthy and influential family that even funds the 3WA. This is Yuri's big chance to finally date and marry rich, and the boy's chance to be with the real Yuri! But the boy only cares about his Yuri's ideal traits of being sweet and innocent, and shuns the realistic ones that she and every girl have. Can Yuri win him over without losing herself in the process?
