[Fumino] When Accelerator Meets Nakahara Chuuya

As the title says, when Accelerator, who masters "vector operation", meets Chuuya Nakahara, the gravity user of "Araba Tu"... Very short story. Accelerator traveled through time and left the series ten minutes after the fight. Fight, ten minutes. That's right, that's the restriction. Intention: fate, wonderful beyond words.
