So are the writers going to disregard the "S4 can only create their own brands" rule that has been established in-universe? Well, that's fine by me. From the way I see it, this can occur only if Yume doesn't make it into the S4, and to be honest, I personally agree they should scrap off that rule altogether.

Yotsuboshi Gakuen has always been too hierarchy-based and elitist for my liking; it's always "if you aren't S4, you can't do this, can't do that, etc." The fact that Lily, a non-S4 admin who seized the chance to create her own brand shows that this rule can be broken if necessary, and if the main character of the series (Yume) manages to emulate her without even joining the S4, this will eventually pave the way for non S4 students to create their own brands regardless of rank or status. That said, the name "Berry Parfait" suits Yume just fine.
