わたしはあたらしいまんがをよみました。とてもおもしろいです。青年まんがです。 It's very funny, but also kind of dark, which makes it even better. I stumbled upon it a couple of days, and now I'm following it. The title is translated into "Lucifer and the Biscuit Hammer". You'll understand the title if you read it. You can find translations of it using Google (you can pretty much find anything on Google).
