It's been comical but definitely not lighthearted with the amount of rape and dubcon that it has portrayed within those same 5 volumes.
As for your asymptomatic intelligence with no media literacy, if you've read this far and didn't understand what the author meant to communicate through a certain character it's not my issue, it's very clear that it was a self insert and a reflection of their art journey, bye XD
I don't think you'll even read this but it's still out there for others to analyze with me so whatevs.
I think literature classes are not working they way they used to because this is basic media analysis, on top of it you're making up stuff about me, I never claimed to know the author like that and it's weird that's the first thing that came to your mind.
Back to the story-author parallels, it's clear as day and very easy to analyze this author's character based on the subplot of Koma as a character, authors tend to let slip reflections of themselves in their stories and Koma is a very obvious example of this.
Koma is a character with taboo interests who is generally fun and doesn't have any intention of harming real people or his partners, but this character feels pressure and shame because he's afraid ppl will misunderstand him and think he actually wants to recreate the gorey scenarios he enjoys. That's why he tones down his interest in front of others and doesn't open up easily.
In this moment is easy to see a glimpse of Harada in this character, the current years we live in it's clear fandom spaces have changed drastically mostly because of US influences in it and their weird practices like witch hunts when someone doesn't adhere to a certain moral code, if the art they create is taboo there's a possibility of ppl trying to attack the artist and "cancel" them.
You don't have to be a mastermind to understand Harada as an artist, it's clear in this manga what their concerns are concerning this new young public with a slowly cementing puritan mindset.
It's okay if you choose to ignore the hints but it's still there for people who want to understand and read socially and psychologically into it beyond "haha sex, joke, sex again"
The ppl new to Harada-sensei are not ready for the real fucked up stuff to come, this is the most tame manga I've ever read of her and it's funny how ppl are proving her right by reacting so aggressively to even this tame work of her.
The whole theme of finding joy in the exploration of weird stuff that was navigated in the first volume flew over everyone's head, it's really sad to see how Harada feels limited by this new internet culture of shame in this oversensitive era ( ̄ε(# ̄)Σ.
