The premise sounds like it’d make for a very interesting story political and conflict wise. How will the citizens react? How will the government react? The author could also tackle some really important subjects of prejudice (judging new species by their looks; a huge part of the reason we even have racism and sexism is that the human race (and most species) are inclined to form groups and see anyone not in their groups as the enemy. Not looking like “me and everyone I know” is an easy way differentiate groups and dehumanize people; imagine how it’d go for other intelligent species), philosophy, mob rule (fear makes citizens VERY dangerous), imperialism, fight for resources, greed, and so much more. Really with a premise like this, there are so many unique and interesting storylines we could get, and so so much that can be done for world, character, and society building. However, that’s what makes this risky. Its so easy for the author to disappoint when there are this many possibilities. Not to mention this isn’t nearly as generic a formula as the usual isekai, so whatever the author does has the risk of being unliked and he could mess up. My question is, does this live up to the hype I immediately formed from the description? Well, no use just asking. Might as well dive right now. Hopefully this is really good.
