Commentary:
I've been looking forward to revealing her power since the beginning of the story and now it's finally arrived. I had originally planned for this page to be animated, but there wasn't a good loopable action I could have done with her current skill level. Luckily I did an animated page earlier this chapter, so that quota has been met at least.
Lubo's face in the last panel is supposed to be reminiscent of Auda's reaction to seeing Lubo use his power for the first time back in Chapter 18. I made Lubo's face less comical looking, however, due to this being a first time reveal to the readers and not just Lubo, so I gave him a more genuine face. Auda's reaction was more comical because the reader already knew about his power since the first chapter.
But yeah, now you know why Lubo was asked to come to the beach alone. It just so happened to be the perfect spot to use this power with no one else around.
