This is a personal interpretation of the events after the story mode takes place in JSAB. Blixer is regretful, Barracuda is gone, and the effects of the corruption were much more rooted into Paradise than anyone could have anticipated.

Paradise was a lovely place.
Well, mostly.
It was long ago torn in two by opposing traditions and mindviews.
In all the conundrum and the busy hustle of citizens around her, Cube used to visit a strange fellow in the caves.
He looked like the cacti around Paradise, but he was much more gray, and had a more humanoid body.
She would come to visit this strange cacti that couldn't move, this stranger that called himself "Boombox".
She would tell him stories from the outside world, and he would tell her fantastical stories from where he came from.
He would change the topic, however, when the conversation got to where he came from, or how he got there.
One day, she told him about the soon visit of someone special, someone powerful, who would be able to once again reunite Paradise.
He instantly seemed interested, stating that he would like to meet this figure of power if it was possible. Cube decided Boombox was a nice enough person. Maybe she could even convince them to find a way to free Boombox so he could come see paradise as well.
So the next day, when they had spare time, Cube snuck away with Cyan and a power triangle.
All she wanted was the best for her friend.
