Pretty interesting to see both MC and the presumed hero Amiyu are not exactly lawful-aligned or even good-aligned, at least as shown so far. MC is quite cunning and strategic for only doing things that bring him benefits and information that he wants according to his personal agenda, and Amiyu isn't really the kind saintly girl heroic hero too but more about doing stuff for her own sake resentfully and don't exactly care about other well-beings too. Both are giving me chaotic-good or chaotic-neutral currently. Though I can tell some readers are not used to seeing main characters that aren't necessarily lawful and/or good aligned (which most of the hot-blooded typical shounen MCs&co. usually are) and got confused/frustrated with how MC would rather prioritize gaining intel than eliminating risks of casualty when first coming across the magic circle, and the supposed hero is also such a close-minded arrogant bitch.
Personally, I think chaotic characters are fun to read because they tend to be less predictable and have personal secrets/agendas that get me curious to see how the story goes. Though, I have to say darker/chaotic stories are more enjoyable for readers who are in a chill-er mood, who are not in a bad mood of feeling stressed out by reality/personal life and looking for fantasy escapism. Usually, I'd take a break from darker/chaotic stories if I'm not in a good mood and read the more lighthearted type of stories that are generally about healing/mofumofu/slice-of-life/cooking/cute romantic fantasies, or even inspirational/motivational hot-blooded sports genre, and determined in dropping series that I honestly just don't enjoy reading instead of piling up my following-backlogs feeling like I "need" to enjoy reading them because they're supposedly what I like given their genres/themes/settings, which doing all that actually helps my overall reading experiences to be better.
