Yoko is a pretty, tall girl with an incredible figure for her age. Very mature and quite knowledgeable, she prefers to think things through before charging head-first into a battle. She is also a great sniper with her oversized rifle.
After the grueling battle to defeat the Spiral King, Lordgenome, the surviving members of the Dai-Gurren build a new capital over the remains of the royal capital. However, unknown to the public in general, Rossiu Adai have led a secret project to access Lordgenome's memories and learn from it the history behind him and the Anti-Spirals.
Tainted by the despair of Lordgenome, and the truth about the Anti-spiral and the Spiral Nemesis, Rossiu fell into despair, and took the suggestion of Lordgenome, limiting the number of humans by means of arranged "accidents". He also acted on the advice of Lordgenome to remove those girls that have the highest chance of producing humans with an artificial dummy gene, which, upon detection of high amounts of spiral energy, would trigger a transformation into an Anti-Spiral scout.
Amongst those girls are his old comrades Yoko and Nia, along with his old charge Darry. By the time those names came up in his reports, Rossiu is so far gone the he did not hesitate to condemn them, selling them to a extra-dimensional slaver.
