Having fun in school, doing homework together, cooking and eating, playing video games, watching anime. All those little things make up the daily life of the anime-and chocolate-loving-Izumi Konata and her friends.

Paris, 1742. While investigating the murder of his beautiful sister—Lia—D’Eon uncovers an evil which casts shadows in both the palaces of kings and the dark alleys of Europe. It is a dark and strange power—one which allows Lia’s soul to return from beyond and possess her brother in order to avenge her own death.

It's a gorgeous, spacious mansion, and four handsome, fifteen-year-old friends are allowed to live in it for free! There's only one condition—that within three years the guys must transform the owner's wallflower niece into a lady befitting the palace in which they all live! How hard can it be? Enter Sunako Nakahara, the agoraphobic, horror-movie-loving, pockmark-faced, frizzy-haired, fashion-illiterate recluse who tends to break into explosive nosebleeds whenever she sees anyone attractive. This project is going to take more than our four heroes ever expected: it needs a miracle!

Antique Bakery is a small bakery that's run by four handsome men. Tachibana the owner, Chikage the one who was sent to watch over his childhood friend, Ono the "demonically charming" master pastry chef, and Kanda a former boxer.

In the big city of Yanagihara, the masses of people and buildings make it a bustling place to exist, and yet, people will meet and fall in love here in this city.

A group of mysterious white-haired children has been spotted at different times and places in Europe for over 500 years. Always with the looks of 11 years old, they behave way more mature than they should be, never grow, and seem to have supernatural power.

Now, in the year of 2012, an athletic boy named Tohma is about to be involved in this centuries-long mystery.
