I'm afraid I have no clue about the author of 'the tearsmith novel'. It could be a relatively unknown author or a new release that hasn't gained much popularity yet, which is why there's little information available about its author.
I'm not sure as I haven't read it specifically. It could be about a character named Tearsmith who has various adventures, or it might deal with themes of sorrow and redemption given the name 'tearsmith' which sounds like someone who works with or is associated with tears.
The 'No Guns Life' manga hentai typically involves sexual or risqué themes based on the characters and story of the original manga. It's not for a general audience and often found in specific adult-oriented platforms or communities.
The main themes could include critiques of political systems, highlighting the underhanded tactics of politicians, or serving as a commentary on social injustice. Sometimes, they might be used to convey the idea of a snake-like influence that is corrupting or manipulating the political landscape.
