Anime Profile: Manyuu Hikenchou

Manyuu Hikenchou takes place in an alternate version of Japan's Edo period where large breasts are worshiped and having flat chest makes you less than human in the eyes of most. Over the years, certain families have been able to develop secret techniques to help increase the bust lines of their women, giving them high status among the people along with wealth and influence. Once such clan is the Manyuu.

The Manyuu clan's successor is a highly skilled kunoichi (female ninja), Chifusa, though she hates the way everyone is obsessed with large breasts and refuses to be a part of it. She leaves, taking the sacred scroll which details a technique for stealing breast size, meaning the technique can not only shrink an opponent's breasts but then increase the user's own breast size by the same amount.

Now Chifusa must travel the land with her loyal companion, Kaede, avoiding the assassination attempts of her old clan while attempting to find the secret to increasing the breast size of other women in order to make everyone equal. Can she do it?

This anime has a lot more nudity than most ecchi shows, having no problems frequently showing bare breasts and how they move in various circumstances such as when washing them, bouncing them, or swinging them around as a distraction. I'm amazed this was ever able to air on television, though I did read that it was heavily censored for most broadcasts.
