Thema

If one wants to follow the path of magic, he or she needs a Thema (theme, topic, subject, or matter). Everything starts there and also comes together there. Superbia, Ira, Acedia, Invidia, Avaritia, Gula, Luxuria. These seven deadly sins act as Archives, and within them, you find a thema associated with that archive. Your thema is the thing that's farthest from yourself. So the things further from one's own common sense is what makes true "magic". Most people will choose an Archive and Thema that is opposite of what their personality is, as that appears to be the easiest for them to use since magic is irrational by nature, in other words, they must think in a way contrary to themselves.

Superbia (Pride)

 * Justitia / Iustitia (Justice) [Justitia and Iustitia are both correct translations] - Thema of Mira

 * Unspecified - Thema of Lugh
 * Spero (Hope) - Thema of Levi

Trivia
The term Baltan in the manga is a wrong translation of a fan. Because of the very small characters beside the larger complex characters (Kanji) that is found in Volume 2 Chapter 20, they mistook the word. There's a "ha character" in Japan where you can translate it into "Ba" or "Pa" when you add a specific symbol. Same goes with "Ru/R" and "Lu/L" too. The translation is not now fanmade, it has an original source, a teacher of Japanese language. So Baltan in manga does not really exist, that's why it was stated in the anime that it's Partum (even without using subtitles).
