eXceed Gun Bullet Children

Humanity is at war with vampires and deviants. Humanity's last line of defense is a group of children trained to cast powerful magic that can take on the demonic hordes, but at the cost of much of their lives. They are called the Gun Bullet Children, resembling the bullets of a gun. The time is NOW! A vampire invasion has been detected in the airspace above Tokyo Portal 5. Preliminary reports speak of over 500 Vampires and accompanying Killings Dolls with reinforced hordes of rogue humans. The first line of defense has been wiped out and the Gun Bullet Children must counterattack and stop the invasion.
