After first reading Boku, I made this post in which I said that I found Jouchi really irritating. Now that I'm getting ready for the RPG, I went back to read the manga more closely, and I think I have to revise my opinion slightly.
So now that I'm caught up on Harudaki, I finally got around to reading Boku no Koe, and I find that I have mixed feelings about this series. Contains spoilers below the cut...
