A young lady by the name of Renge Houshakuji is shown the photo of a young man her father wants her to consider, and she immediately boards a plane for Japan. She appears at the Host Club and immediately rebuffs Tamaki's friendly advances in favor of pouncing on Kyouya, claiming to be his fiancé.
It turns out that Kyouya is the spitting image of her favorite male character in her favorite dating sim video game. Because her father has a significant business relationship with Kyouya's, he tells the club to put up with her for a while.
Renge appoints herself to be the club's manager and starts filming a movie, assigning the club members new roles. Some of the hosts are game, particularly Tamaki and the twins, although the enjoyment wears thin pretty quickly. Eventually Kyouya tells Renge off, and she refocuses her attentions onto Haruhi.
