Light Novels are well known for being light on writing quality but this really takes the cake.
Our protagonist is moody and unselfconscious; he only manages to seem likable by comparison to the setting which never makes even a desultory pass at believability.
It's never explained why anyone would want to summon random strangers to save the world or how this circumstance of cyclical crises was set up in the first place. Just once I'd like to see one of these cookie cutter kingdoms summon an actual modern day, professionally trained mercenary or soldier to save their kingdom. In fact I would settle for a fantasy setting that was something other than "vaguely european".
You can see the psychological deficiencies of the author play out nakedly in the work, our protagonist is an otaku of no particular will, personality or intellect. He never speaks of having friends and he casts off the bonds of family without a backward glance so that he can serve his true role as the reader's wish fulfillment fantasy stand-in. He arrives and immediately the whole world is set against him, which is not coincidentally the feeling that most self-involved immature fools have, its an emotional attitude best suited for a child.
After his "betrayal" an event that the author clearly lacks enough experience of the world to sell to any discerning reader; Our man the shield hero becomes embittered and jaded. Few things are more disgusting than a privileged 21 year old who thinks they've become worldly.
Its almost like the author was trying to be Freudian by making it clear that the only type of woman our protagonist can relate to is one who has literally been turned into an object for sale or purchase. Few guesses as to whether our protagonist has ever has a girlfriend.
More than a few light novels have protagonists who seem to jump into slavery with no sense of moral compunction, I don't know if this is just an attribute of this poorly composed genre of fiction written by and for crappy people or if Japanese culture in general just has weak moral fiber; I dearly hope its the former. Hopefully light novels are as representative of Japanese culture as Twilight and Fifty Shades of Grey are of American culture.
I would recommend this book for otaku who don't read books.
Is anyone translating real japanese novels? The kind that amount to more than wish fulfillment for moody teenagers? Where can I find those?
