Yukiko Ogawa

The story focuses on high school girl Nagisa Yukiai who lives in a seaside town. She has believed her grandmother's story that spirits dwell in words and they are called "kotodama" (word spirit). One day, she strays into a mini FM station that has not been used for years. As an impulse of the moment, she tries to talk like a DJ using the facility. But her voice accidentally broadcasted reaches someone she has never expected.

The Dematerialization Phenomenon, in which the real world becomes digital, has become a problem and must be resolved immediately. After hearing of this incident, Netto and Rockman left off after their father and Network Researcher, Yuuichirou. He also had found news of an invasion in the computer of the Trinity Brain trust company: 'The Earth itself will understand the way things stand in the cyber world'. In order to destroy the program causing the incident, Netto and Rockman have to go deep underground. But old enemies await them there, as well as new ones. As they fought each other, the vicious cyber-life, Nebula Grey, awakens. The Dematerialization Phenomenon will not be stopped unless Nebula Grey is defeated.

Two years have passed since the Great War. Akito and Yurika have vanished. The Jovians and the Earthlings have joined forces and Ruri is now captain of Nadesico B. As the popularity of Boson Jumping grows, a vast transportation network has been developed. Dubbed the Hisago Plan, this network of Chulip portals holds the answers to the mysteries behind Bose particles and their power. If those secrets should fall into the wrong hands, it could mean big trouble. And big trouble there is. A Martian splinter group has launched an offensive, leaving the United Forces befuddled and desperate. So much so, in fact, that the former crew of the Nadesico is called back to active duty for a special unsanctioned mission-to save us all. Does this menagerie of misfits have what it takes? Who will win the race for the Boson technology? And what the heck happened to Akito and Yurika?
