If you loved Neon Genesis Evangelion and Change 123, then I suggest you better read this. You'll sure get hooked to it. It is still running and at chapter 41 for the moment. It also has an anime adaptation.

From Wiki

The series revolves around an extraterrestial force called the Nova that are invading Earth, and genetically-engineered girls called Pandoras and their male partners called Limiters are created to combat them. The story centers on Kazuya Aoi, a Limiter whose late sister was a Pandora, and Satellizer el Bridget, a Pandora with a cold personality who is known as the "Untouchable Queen" for her intense aphephobia, both enrolled at West Genetics Academy, a special school that trains Pandoras and Limiters alike to fight against the Nova.The story follows Kazuya's friendship with Satellizer, the students of the Academy and Earth's war against the Nova.
