Query: Not believable at any level

It became obvious that the author loosely bases his tales on very little fact. This isn't to say that there aren't criminals and ne'er-do-wells in Japan (as in the rest of the world) but if you were to pick a crime...say, stealing motorcycles...and then write a story with two main characters, a love interest, a few antagonists, you'd be doing exactly what is done here. In the end, I think it a little sophomoric to think that we should be shocked by what we read, when what we are reading here is obviously fiction based on fact. Whenever conversations between two characters takes place, you know the author wasn't present for those conversations, whenever a crime is discussed, you know the author is guessing as to how it was done.
