Yuri and Kei are given accommodations at an all-girls boarding school from the 20th century. Yuri finds the life as an exchange student a lot of fun. Kei could care less, until she learns about some ghost stories about the school and experiences some of the horror.

The rain catches Yuri and Touma in the city and they end up at a flower shop where Touma falls in love with a girl who works there. Kei and Yuri pick up on the computer geek's change in mood, and readily give him love advice on the scary thought of asking the girl out.

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?
