Earth Successor

 * In the near future, humanity is struggling with a planet-wide famine.
 * To solve this problem, scientists develop a new genetically-engineered species called "Ruffians" to raise as food.
 * These creatures are herded in northern Japan until they mutate and begin attacking the country's citizens.
 * An international peacekeeping organization called the Armed Volunteers tries to stop the creatures, but they also oppress the Japanese people. Another group, led by a mysterious woman with unusual powers named Achi, rises up to defend Japan against the Ruffians and Armed Volunteers.
 * Between battles with the Ruffians and Armed Volunteers, Saki, a member of Achi's group, unintentionally morphs into an enormous Ruffian after falling into a rising tide of blood filling up Tokyo.
 * To bring Saki back to normal, Achi orders Airan, Saki's partner, to shoot Saki, but Airan refuses to do this.
 * In response, Achi places Airan into a dream sequence, set ten years in the future in New York City. Here Airan meets her future son she shares with Saki, and sees a Ruffian Saki rampaging through the city. The dream ends with her shooting Saki, and then waking up to realize that Achi manipulated her into doing the same thing in the present.
 * Achi reveals that she is not from Earth, and that the war between the Ruffians and the Armed Volunteers was her ploy to groom Saki into an ultimate warrior to use in a cosmic battle with extraterrestrial beings. She also reveals that plans to have Saki help her rule the new Earth she is about to create.
 * Achi creates a new Earth and begins attacking the current Earth.
 * Saki, now in a part-human, part-Ruffian state, combines with Airan to revert to his full-Ruffian form.
 * Saki and Airan successfully destroy the new Earth and send Achi drifting into space.

Star Successor

 * There are two dimensions present within the universe: Inner Space and Outer Space.
 * The leaders of Inner Space, known as the Creators, created and cultivated several Earths populated by humans to defend against Outer Space. Whenever humans stray from their intended path by attempting to bring peace, the Creators wipe them out and create a new Earth.
 * Outer Space sends a reconnaissance unit in the form of a human girl to investigate humans. However, in the process of infiltration she loses her memory and wanders to the ruins of Earth-4 instead of the human-populated Earth-5.
 * An agent of Earth-5, Isa Jo, is sent to find and kill the Outer Space infiltrator, but after observing her he concludes she is harmless.
 * Naming her "Kachi," Isa decides to protect her.
 * In response, the Creators send out a group known as the Nebulox, led by Isa's former ally Deko, to tell Isa that Kachi is a monster capable of destroying entire worlds, and that he must destroy her. When Isa refuses, they try to kill both Kachi and Isa for his betrayal. The "Keepers," lifeforms which have worked to destroy any supposed contaminants to Earth-4, attack humans and invaders.
 * Isa goes on the run with Kachi, seeking to board an air ship that will take them off the planet. Isa and Kachi's attempts to escape are thwarted by the Nebulox until they eventually decide to face them head on.
 * Isa changes into a ruffian form, an ability he inherited from his father, Saki, but he merges with Kachi in order to control his new power. They pursue the Nebulox into space, killing them one by one.
 * Kachi recovers her memory returning. She reveals her real name to Isa: Achi, She also tells him that his decision to protect her from the Nebulox was a mistake after all.
