I feel this chapter should have been a tad bit longer. Like... it feels like it's missing something from it. It kind of hinders it. Which is funny, because the pre-class battle, it was taking too long. But, these are supposed to be two of the "main characters" in this story, right? Souta being one of the POVs, and Kaoru being the other. Her starting to suspect him should feel more impactful. It feels like they kind of glance over that specific part of the story.
Honestly, there seems to be a good story in this manga, but it isn't executed well, so the story suffers because of it.
