I had such high hopes for this, after watching the first few episodes. It looked to be an steampunk/horror mix, although not as interesting as D-Gray Man. By episode sixteen, I was through.
Although I was no fan of the increasing profanity, what killed the deal was the fact that the mangkata behind the series had not planned out what was going to happen next. You know the deal. Mystery characters start showing up, and this redefines everything you’ve seen and experienced up until this point, because the guy was too lazy to use any foreshadowing. As a result, the series took a dive into soap opera land, where main characters become bad guys because, because, well, I dunno. With the plot on ice and the characterization gone, I was gone.
Now this series was never really deep and it was at times a bit too over-the-top with all the speech-making, but the characters sucked me in. Toshiko-san is pretty much what every geek guy wants in a girl: someone into the same stuff, and thus someone that gets him, and can respect him. The opening theme song shows this well: the two of them together charging hard at some off-screen enemy.
Ah well, another case of anime` fail. Welcome to the graveyard, Busou Renkin.
