- Hey, It's That Voice!: Victorique's voice in the anime has been many rich and/or powerful young girls in the past. Grevil is just a doctor, an overenthusiastic boxer, and Chinese Electric Batman.
- Schedule Slip: Episode 10 was delayed a week, and Episode 11 was delayed until the 1st of April because of the 2011 earthquake and tsunami in the T˘hoku region of Japan.
- The country of Sauville really existed. In the real world, it was known as Savoy. It became an independent Duchy somewhere during the Middle Ages and existed as a country until it was annexed by France in 1860 during the Italian unification movement. It was mostly located on the slopes of the Alps (hence the mostly mountainous landscape in the series), but also had control of the city of Nice, which was a port city. While, of course, the history and the place names of Sauville are made up, the geographical location and the landscapes are fairly accurate.
