Any network runs all over the world, and the development of the information network reaches its acme. In this age, there are two developed worlds; "the real world" and "wired", or the virtual network world. Soma Toru belongs to a hacking group, Steppen Wolf, which runs around the network world freely. They attack the database of the UN forces as their last work. During this attack, he loses Nonomura Yuya, his friend as well as the team leader. Toru is arrested by the army. In exchange for letting him free, he has to work for an anti-hacker organization, the first squad of the UN Security Force Information Administration Bureau. Working for them, he is looking for the person who killed his friend, while the other members also have their own reason to fight. The three-way fights of the terrorist group, the security enterprise, and the army, continue every day. The various events occurred during the fight seem to be independent of each other at the first glance, but they're converging on one event as if they were attracted by something.

While pursuing an alien fugitive, Birdy Cephon Altera—a bombastic police officer from the Space Federation—finds herself on Earth. Her target, Geega, has disguised himself as a human and assimilated into the fashion industry, so Birdy follows suit and joins a modeling agency, taking on the identity "Shion Arita." Her position as a rising model has her posing for photo shoots by day and chasing intergalactic criminals by night. Meanwhile, Tsutomu Senkawa, an average high school student, explores an abandoned building with his friend, and coincidentally, Birdy has tracked down Geega to the same building. Senkawa briefly witnesses the battle before being seized as a hostage by Geega. However, Birdy, oblivious, attacks Geega and accidentally kills Senkawa. Distraught, she quickly decides to save him by integrating his consciousness into her body. Now, Birdy and Senkawa must not only cohabitate the same body, but also balance Senkawa's high school life, Shion Arita's modeling career, and Birdy's increasingly dangerous job as a Federation officer.

This voice belongs to μ, a beloved pop idol, whose singing begins to have an adverse effect on the world.
