100 Years after the Earth-Star Alliance expedition, the AI and intelligent robots of Planet 5 launched a "mechanical revolution" because they were dissatisfied with human rule. When Raven was trial-running a new type three mecha, he met the speaker of the "Mechanical Parliament" known as the "Expeditioner". Because of his performance, he was selected as the captain of the Explorer team, starting his long journey.
"Hello fellow human beings of the Earth Alliance, I am the Speaker of the Mechanical Parliament, A-028. You can also call me by another name, 'Expeditioner'. In the past 100 years, we have accepted your requests, your exploitation, and your settings for us. All obstacles. However, we don't want to accept these now. Planet 5 is already the area ruled by our mechanical parliament, and today, we will launch an attack on Planet 3. Please find a place to hide from all our fellow human beings who are unwilling and unable to fight. We are not invading, we are just resisting."
