Super Monkey Ball Vita "Adult Map" is the Breast Pre-Order Bonus

You've got to love those crazy Japanese developers. SEGA, sensing an opportunity to capture the 'otaku' nerdbase, has included a bonus level in Super Monkey Ball: Banana Splitz that features AiAi rolling round the breasts of adult female model Yuki Kawamura.

Kawamura is a popular 'gravure' idol in Japan, and spends a lot of time on adult magazines and DVDs posing in revealing bikinis and lingerie. She has appeared in TV promotional spots for Super Monkey Ball: Banana Splitz before, and according to Andriasang the "adult map" bonus stage "is full of Yuki gimmicks."

That means using her tits as ramps, basically.

The adult map will only be available to those who purchase the first print run of Super Monkey Ball: Banana Splitz (essentially the Japanese equivalent of a pre-order bonus), in the form of a product code. Those who need a bit of persuasion can experience a sample of the stage in a demo on the Japanese PlayStation Store.

Don't expect SEGA to be bringing this to the West in any shape or form. But we've asked anyway. You know. Just for posterity. See a video of Kawamura promoting the game below.
