Chapter 1

A sudden, unexplained catastrophe hits Japanese cities. Following the catastrophe, robots become more and more commonplace, helping to rebuild the affected areas. A mysterious black-haired girl is shown waiting to cross the street.

Five years later, the story shifts to a leading robotics university, where a young Ochanomizu runs back to his dormitory with a sandwich and some groceries. He passes by three girls in the same class as him, who don't notice him calling out to them. He tries to play it off, but becomes embarrassed about it.

While still trying to play the situation off, he accidentally runs into Moriya Tsutsumi and knocks him out of his wheelchair. Horrified, Ochanomizu tries to help Moriya back into his wheelchair. The two talk to each other, and it's mentioned that Moriya is one of Japan's most promising young geniuses.

Moriya snaps his fingers, allowing his own wheelchair to pick him back up and place him back into his seat on his wheelchair. The two part ways, and Ochanomizu becomes flattered that Moriya talked to him. Moriya turns to see a red-haired girl approach him, who calls him “big brother”. Moriya calls her “Motoko”, and the chapter ends.
