- I have read the manga up to chapter 17, and much further into the novel. Hmm this is a nation/city building story with a creative and rigid magic system. When exploring spells, mana and their characteristics it feels as if I'm actually discovering them with Ars (MC). The world seems very distinctive, and does not fall into a lot of trappings of other isekai. From what I have read of the novel it seems that the manga is a faithful adaptation with no inconsistencies as of this short review. If you like consistency of magic in your isekai stories I think you will like thisone. (◠‿◠) \(‾▿‾\) (/‾▿‾)/
