Toaru Majutsu no Index VS Durarara!! Kamachi Kazuma X Narita Ryohgo

This is a story of distortion.

A story of twisted distortion.

They were never supposed to intersect.

The world where magic and science stride and the fate of the world is hung over the ridge of a sharpened blade.

The world where the fairy strides through the city and immortals and vampires quietly mingle with the people.

Two people who are not supposed to meet...do so. Worlds that are not supposed to meet mutually encounter each other, connect, mingle―――and then clash!?

With various factors becoming intertwined, the [urban legend] called [The Mystery of the Underground Tunnel] was born in Academy City and Ikebukuro.

Now that the two are connected based on the same urban legend, an unprecedented opportunity to visit each other's worlds has arrived―――Nobody knows what will happen.

The world that opened, the time that closed.

Whatever they encounter and whatever clash occurs, will their hearts get distorted by the trickery? Or will the distortion get corrected?―――Not even the concerned parties have the answer to that.

Kamijou Touma and Celty Sturluson. With both of them embracing their lack of memories, will they get dragged into any kind of distortion in their respective worlds?

As long as the answer leads to peace, there's no choice but to jump in.

With two worlds created, they head towards the never-ending distortion―――.
