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?
