One day, nine-year-old Misaka Mikoto found eleven-year-old Accelerator. From him, she learned about the [Level 6 Shift Project].
After hearing about the experiment, a question she couldn't ignore arose in her kind-hearted heart.
What could she do to make the experiment stop and ensure that the [Level 6 Shift Project] would never be restarted in the future?
A far-fetched but surprisingly plausible answer came to her, and as it appeared, determination flashed in her eyes.
Then, facing the white-haired boy said to be the strongest esper, she spoke...
"Accelerator, let's get married!"
"...Huh?"
