Her position in the series is to be a major plot point  since the Index Librum Prohibitorum is the most powerful weapon in the magical world and is in the hands of "The Enemy of God" who also a member of the science side aka the Imagine Breaker and the fact that Touma is in control of the Index is one the major elements that led to WW3. The series is named after the Index Librum Prohibitorum the powerful magical library and weapon of magic which the girl Index is also named after. She isn't the star character just a very important one to the plot. The reason for New Testement still being called To aru majutsu no Index is becouse it is a direct continuation of the first so it only makes sense to keep the name.
