The Princess Waltz - a dance of whirling blades held to find the princess worthy of becoming queen of Seven Central in the fantasy world of Eldelant. Hopeful candidates travel from all the kingdoms of Eldelant to take part in the waltz, but only one princess will reign supreme...
You are Fukamori Arata, and you know nothing of princesses or waltzes. In fact, your daily life in modern Japan couldn't be any more ordinary - you live with your mother and sister, are woken daily by your childhood friend to go to school, and live a generally full but normal life surrounded by a gang of rowdy classmates. When rumors start circulating about a transfer student to your class, you don't pay much attention - princes from foreign lands don't study abroad here in this day and age, do they?
When Chris Northfield arrives, it seems the rumors might be true. What is an impossibly refined, polite and accomplished young man like him doing at your school? Your curiosity gets the better of you, but as you investigate you begin to realize you're getting into something deeper than you ever imagined...
