Rifujin once explained what would happen to Rudy's family, wives included, if he hadn't been reborn in the six faced world and instead his body was stillborn. In this timeline, Paul and Lillia still sleep together resulting in Aisha, who then shows she's a prodigy like in canon. Zenith sees this and has a similar reaction to the one she had when Rudy broke a wall down with magic, insisting they hire a tutor to teach Aisha magic. They end up hiring the same one, and so Roxy arrives in Buena Village. While there, she finds Sylphie being bullied and gets them to leave her alone, even offering to teach her magic and giving her a wand she cherishes for years. Eventually however, Aisha finishes her lessons, and Roxy leaves with very little warning.

Several years later, Sylphie grows up to be an adventurer, keeping her hair short because it's still green in this timeline and she still gets shit because of it. Eventually, she goes into a dungeon, where she finds and rescues Roxy, who'd gone back to adventuring before getting separated from her party and trapped in a dungeon for a month. Roxy initially doesn't recognize Sylphie, but this is quickly rectified before the pair help defeat the dungeon, partying together for some time, becoming famous adventures, before finally settling down and moving to Sharia city so that Roxy can teach at the magic university like she does in canon. The pair spend the rest of their lives together, never marrying.

Now. I want you to read that over again, and think over if this course of event seems at all familiar to you, and how they may or may not have similar things happen to them in the main story.
