Another thing to add is that I hope Aron asks to be trained by Agnarr in order to not be dependant and useless without him. A major issue I see in those types of VN is the mc being useless without the main LI so Aron asking to be trained and showing being able to fend of for himself would be an ecxelent decision
That is very common in vns and it gets kind of annoying when so many of them resort to the mc (human main characters especially) being weak and inferior and cannot last without the big strong love interest protecting them. I like to see a mc that is more capable in things such as defending themselves, and contributing to the story.
