Two years before becoming the Vikki everyone knows today, she went through a difficult period in her life after years in space. A time that helped her escape the anger and sadness caused by her father's death ended when a member of her space group was killed on a mission.
The separation from the group after this tragedy and the return to her Earthly life on Dreamuria was very difficult for Vikki, who no longer felt any energy for adventure or for ideas for inventions. She felt nothing, except the desire to eat to try to inject some positive emotions into her life.
She returned to her father's laboratory, where she lived, activated her little childhood creation, Unasai, and spent all her days doing nothing, sitting or lying on her couch or bed, watching anime, movies, TV series, playing video games, and, above all, eating a lot.
Unasai, who had been attending to Vikki's every request so that she wouldn't make the slightest effort, began to worry, seeing that she was gaining more and more weight, barely taking a bath, and seemed to have only negative thoughts, despite the amount of stuff she watched.
Unasai then tried to reason with Vikki, saying that her health was deteriorating from doing nothing these days and that she was losing more and more muscle mass, which was being replaced by fat. But Vikki didn't want to know and told her to keep quiet, wanting to watch her anime.
It took a long time for Vikki to emerge from this depression and find meaning in her life, but during this time, she gained a lot of weight, which explains her current weight, especially since she doesn't like exercising.
