Asuta Jimon, a runaway, is wandering the streets at night when he has a chance encounter with a young girl collapsed beside her tricycle. After he offers her some food, she is moved by his kindness and asks him to join her organization, offering him a face mask and a sweet bun. In need of a place to stay, Asuta decides to play along and accepts her offer, adopting the nickname "Dva." Little does Dva know, this cute girl is Kate Hoshimiya, the leader of Zvezda, a secret organization bent on world conquest. However, he soon realizes the true weight of her words as peculiar happenings rope him deeper into Zvezda and its eccentric members—the samurai-like vanguard Itsuka Shikabane, tech-genius Natalia "Natasha" Vasylchenko, troublesome Yasubee "Yasu" Morozumi, ex-gangster Gorou Shikabane, and multi-purpose robot Roboko Tsujii. With "White Light," a powerful organization of justice, and the entire Japanese government against them, can Zvezda really dominate all humanity and let their light shine throughout the world? What does it take to conquer the world?! Every leader of the past has thought of it... but all they have done was to merely dream of its greatness. World domination... nobody has been able to achieve it. Until one little girl by the name of Kate Hoshimiya came along. Kate Hoshimiya will shock the world! How was she able to carry out such a magnificent stunt? So frightful! So glorious! Could this be... the Zvezda Plot?! Let the light of our great Zvezda shine upon this land far and wide!
