Doki Doki Majo Shinpan is a DS title produced by SNK Playmore that revolves around touching little girls in order to see if they're witches. Unsurprisingly, it failed to get a western release.
However, the Japanese absolutely lapped it up and a sequel is now inbound. Entitled Doki Majo Plus, the goal remains very much the same - to interfere with various females until you uncover the telltale 'witch-marks' on their slender, almost childlike bodies.
It's mucho-disturbing (not to mention slightly NSFW), as this trailer shows:
However, eagle-eyed SNK fans will spot plenty of lovely fan-service in that video (kicking off with the Neo-Geo intro at the very start) and it would appear that SNK's recent April Fools joke - which involved a 'fake' retro shooter called Space Radish - is making its way into the game in some form (probably as an unlockable mini-game).
Just as was the case with the first title, there's more chance of hell freezing over than there is of this making its way to the west, but perhaps that's a good thing... video games don't really need any more bad press in this part of the world than they already have, and a title that involves prodding ladies in their funbags wouldn't go down too well with the mainstream press, we're guessing - especially when it's on the same platform as Nintendogs.
