That was the most by-the-books magical girl chapter so far, it was just a normal battle in which the good guys win normally including pervy-but-not-really-serious stuff in the bath afterwards. I guess Sulfur was fun, but I hope she doesn't get focus again, this isn't why I'm reading this.
The only interesting bit was showing that having La Veritas has a purpose.
Each time it's been an "i'm being truer to myself, and what that means" thing. Azul has the serious, icy shrine-maiden side but also a major masochist streak, so hers revolves around redirecting attacks and ice. Sulfur's always been an angry brawler, so of course hers is a yellow element (lightning) and takes the form of a wuxia/chinese martial arts fighter. It works, story wise, because every single one has been like that so far, and explains why Enorme would never evolve; she has too many delusions about the world and herself.
That's also why Baiser was scouted, probably; she has so much deep-seated things about her that conflict with 'normalcy' that she probably has so many things she could unlock....and in doing so, unlock potential in others.
