Miss Monochrome

After her manager Mana-chan takes 19.3 billion of her money, she encounters Manager Maneo while wandering the streets and continues pursuing her dream of becoming an idol while working at a convenience store.

Miss Monochrome was also an idol hundreds of years earlier, alongside a rival who died during an alien invasion. The two had promised to perform together again after the rival's rebirth. Much later, seeing Kikuko on television evokes that old connection and renews Miss Monochrome's drive to become a true idol, even though she no longer remembers her rival.
