On Earth lives a human avatar, not yet awakened to her abilities or divine power, who is one branch of an indescribable being from beyond all multiverses and higher dimensions, beyond the limits of human understanding: a being that can be called omniscient, omnipotent, all-knowing, and capable of anything. At first, aside from sensing that she had never been hurt on Earth, she was basically an ordinary person. All she knew was that her name was Barbaris, and that she was a tsundere, optimistic girl who loved superhero comics, with pink hair in high twin-tails of just the right length and straight bangs. At “16,” because of her innate special nature, she was taken from the orphanage where she lived and admitted to Earth's most advanced superpower research institute, where she became one of its “test subjects.” Under the researchers' development program, she became the most successful and powerful one of a kind: the “strongest superpowered individual.” The first research report on her said that her body contained the power of 100 billion trillion supernova explosions (at the very beginning, that is), and that it might conceal a terrifying, dormant, pitch-black, glitched form of a void personality... And this was only the beginning.
