Later this month, SNK's school girl witch DS touching game Doki Doki Majo Shinpan Duo goes on sale in Japan. To commemorate the event, the first Duo goods have been going on sale, like these illustrated collectible phone cards. They're available individually for pre-order at various Akihabara retailers. Some of the phone cards are riskier than the others. (The maximum one is placed safely after the jump — maybe NSFW, you have been warned!) There's a gallery below if you are curious and the bum bouncing jubblie jubbling trailer above in case you've forgotten exactly what Doki Doki Majo Shinpan is — touching girls to see if they are witches. But, really, how could you forget something like this? Oh, and keep in mind: The pics below are samples, hence the word "SAMPLE."
