Jelaskan Magic dari Zero no Tsukaima

The nobles of Halkeginia are magicians known as "mages" or "magi", and must use a wand or a staff to cast spells. Not all magi are nobles, as some have been forcibly demoted or given up their nobility and use their magic for thievery or to work as mercenaries.

There are four primary magic elements: Ignis (Fire), Aqua (Water), Ventus (Air), and Terra (Earth). Magi have an affinity to one of those elements. There is a fifth element, the legendary lost branch of element, known as void. Magi can combine different magical elements or even stack the same element on top of itself to make spells more powerful. The power of a mage is determined by how many elements he or she can combine. There are four ranks of magician based upon this factor. Those who cannot combine any element together have the first rank, which is symbolized as a dot. Most magic students are in this class. The ability to combine two, three or four elements together leads to a magic user being referred to as a line, triangle, or square mage. In myths, there is a fifth rank called pentagram mage.

One of the major themes is that humans and technology from Earth displaced into the world of Halkeginia are considered to be highly magical, since Halkeginia itself has relatively primitive science and technology. For example, a magical item called the "Staff of Destruction" is, in reality, a human-made Vietnam-era M72 LAW rocket launcher. Other examples of Earth technology, often weaponry, appear throughout the story, such as a World War II era Mitsubishi A6M Zero fighter plane.
