After being saved from kidnapping, you discover you're the daughter of the prime minister and your life is in imminent danger. You are introduced to a handful of handsome bodyguards, and must decide who you want to protect you 24 hours a day.

That's the scenario for one of several role-playing "love games" currently popular in Japan, allowing women to safely spend time with their choice of Mr. Right without actually dealing with a live person - even as marriage rates in Japan fall.

"In the game, you're the lone woman, and the attention of all the guys is on you," said "han-kura," a 37-year-old office worker who uses that alias on a blog dedicated to these games.

The role-playing games are based on characters typical of Japanese manga comics, with all the men slender and elegant. The player becomes the heroine and chooses an ideal mate from several "knight in shining armor" characters, developing a relationship through the choices they make in the storyline.

The games, which can be played on smart phones, are especially popular with working single women in their 30s who feel they don't have the time or energy for a real relationship due to their demanding work schedule, said Kana Shimada, a novelist who writes about modern women and relationships.

"It may be virtual, but if it's ‘a boyfriend from a game,' then you can enjoy it whenever you want," said Shimada. "The games that make you feel the ups and downs of a real relationship have all the elements to get women hooked."

The video game industry has always had a strong male following, but it seems to have found a way to finally capitalize on female users. The sector based on such love simulation games grew by 30.4% with 14.6 billion yen ($177.3 million) in sales in 2011, according to Yano Research Institute.

The games come in several episodes, each costing around 500 yen ($5.98).

The growth of smart phones has had a hand in this popularity through their portability and privacy, said Nozomi Wada, an editor at AppBank, a website that reviews apps.

"The biggest reason for its popularity is that users like myself can play it secretly in the palm of our hands without other people noticing it," said "han-kura."
