Theodora

Theodora, the third princess of the Helas Empire. First shown in the video J. Rakan shows to Ala Alba. During the war she joined Arica and Ala Rubra in the final battle. Not much information is known about her. She is thirty years old in Human years, but she is actually 10 years old in Helas years. She along with Seras, (the Headmistress of the Ariadne knights) and Ricardo, (Senator of Megalosembria) helped Negi and Kotarou with extra training in order to defeat Rakan in the tournament. She tells Negi that she was a good friend of Nagi and Arika and that she knows what happened to them. The most important question from Negi: Is Arika his mother?, but Theodora can't tell Negi the details. Because before he has reached full manhood, she can't tell him about this worlds (Magicus Mundus) affairs. In the end of the chapter, Theodora makes a pactio with Negi. On Negi's pactio card it seems he is holding an item like the spellbook Nagi used. His artifact is a card case that allows him to summon and use his ministra's artifacts and abilities associated with them. Source: Negima Wikia
