I agree with most of what you said but I think "Just having fun" and not interpreting the characters does a disservice to the story. the reason we play is to get to know the characters(and the NSFW parts) and if the story does that poorly in a way it should be pointed out. the moral hypocrisy makes me not want to see half of the characters succeed as to me they are terrible people that refuse to acknowledge that. like being hot can only get you so far when killing a whole kingdom women and children included is on your resume and your reasoning was "for the lols" but still expect people to be sad for you when you talk about your backstory (yes im talking about aki). I cant force you to pay attention to the characterization but the fact that you need to UN-immerse yourself instead of getting invested shows issues in the writing. at least in the morality department. My overall opinion of the game is much higher but still.
(this is my second account as my PC is like 2000km away so I made a new one)
I am not trying to say it does the moral aspects well or that Aki or his companions are justified in their actions or even that this part of the story is one that should be ignored.
The flaws are present and should be acknowledged and I may have not expressed myself very well in my first comment.
I do recognise these issues in the writing and characterisation of the characters and how they are being very much terrible people but hypocritically expect everyone to feel sorry for them because “I lost TWO people close to me!” Or “The Knights murdered ONE person close to me!”
I am saying that despite that flaw I can still find enjoyment in the visual novel in the aspects I find work well or even great. So despite this being a pretty obvious flaw it does not ruin MY enjoyment as much.
If this is however something you can not get over or find to be impossible to look past for the moments that do work then that is totally justified, you read/play whatever you like and whatever you think works. I am just saying how this is for me not a total deal breaker and I can enjoy it.
It is however really simple to fix the moral issue.
Just remove Aki destroying the whole kingdom bit with 0 issues in a instant just let him kill the king himself and that’s it.
It would still keep the aspect of the ruler of the gladiator city hearing of the kings death and that creating some issues with the black ice Aki ever so openly uses but it would also fit more with how they behave in the rest of the story and their characters.
Aki had acquaintances in the kingdom and people who were nice to him as seen in his flashbacks and he when in other cities or kingdom or even immediately after meeting the other demons behaves nothing like this city devouring sociopath or this very cold person so I really do not see the characterisation of him in the beginning fitting with the rest of the story.
These tiny fixes can be applied to every other character and all just makes more sense except maybe red who may need a bigger rewrite making him not a literal psychopath who multiple times tried and would have totally killed us if we didn’t give it our all to LIVE.
