Blue Reincarnation

High school student Kasha Lain was involved in a kidnapping incident at school. She was rescued by a mysterious girl wearing a black trench coat and was forced to follow her on the road to escape. The wanted order from the Continental Congress, the pursuing agents from the Continental Research Institute, the super-era weapons falling from the sky... All of this shows that there is a more powerful and mysterious force behind everything controlling everything, and Kasha herself seems to be hiding some secrets that she doesn't know yet.
