The secret plan that was made to empower Accelerator has beesunk to the ground by the right fist of Kamijou Touma.

Accelerator, the person which the secret experiment was built upon, is felled by the right first of Touma. Air, wind, atmosphere, all this was grasped by the hands of the Accelerator, all this through its vectors, to strike down Touma. All of this, is an attempt by the Accelerator to surpass being the "Strongest" and reach "Invincibility" at last, and in this, knocks Touma down.

As her surroundings tremble at the sight of Accelerator trying to achieve absolute power, Mikoto attempts to stop it herself, for she was the one who gave birth to this "experiment," and allowed this broken man before her to involve himself.――However, this would ruin Touma's plans in taking down the predictions of Tree Diagram by having the "Weakest" defeat the "Strongest."――

The only one who can stop this now are the "Sisters". With this, Mikoto asks for her sister, Misaka Imouto, to "protect his dream." Finally, it is come to the end Kamijou Touma and the Accelerator face each other once more for one final clash.
