This here is my favourite chapter. It has a cute girl—what more do you want?
Episode 2 of Casio Academy, a manga by the company Casio, part of their campaign against counterfeit calculators. Yes, it's weird. You have to through a tedious process to access it: Firstly, you have to create an account with Casio. Secondly, you have to *verify* your Casio calculator (and only select newer models can be verified). Thirdly, now you have access to a game, a horrendously boring, dull, and bad game, and you have to rack up 5,000 points with each character (bar the first) to access the ending to their manga chapter. So you'd have to play the game over and over again to get all chapters of the manga.
