His status changes when the Upgrade System awakens, allowing him to transform a dying unit into an SSS-rank masterpiece built from scrap. He begins a rapid ascent, upgrading one unit at a time. The Mechanicus, a shadowy elite group controlling the world from the top, views themselves as untouchable. They have never faced someone who converts junk into legends. His Mecha Girls remain fiercely loyal, ready to burn the world for him.
