Advertising in manga? What better place? Advertising cigarettes in manga? Even better. Get kids when they are young and fantasizing about super powers and defeating evil. While I believe this practice is less common these days, some of the older manga of the late 80s and 90s had this advertising so in your buried-deep in-manga face, they might as well just had a character transform by cigarette.
In the classic Manga ダイの大冒険 (Dragon Quest), the main character Dai feels embarrassed and small due to blowing up something with magic lightning that he shouldn’t have blown up with magic lightning (Don’t worry Dai, it happens to the best of us.)
So the scene needs a good visual way to show how “small” Dai feels. Hmm, what is something small? Hmm… Duh. Cigarettes.
Nice. And the Mild Seven label is nice and readable. Forget the fact that this is a high fantasy world with dragons and wizards. Cigarettes have their place in any world.
