Hiyori and Bishamon (female characters) have bath/shower scenes infrequently over both seasons. Bishamon, a goddess, is fully naked a few times, with a thin strand of her hair just barely covering her breasts so that it isn't *technically* full toplessness. Buttocks are also seen from the back/side. Whenever nudity appears, it is always censored to some extent by environment, hair, or limbs, even if just barely.
There are panty shots from some of the girl characters in both seasons. Characters include Bishamonten, Kofuku, and Hiyori.
A doctor listens to a teenage girls heart, her bra and belly button is shown
One character attempts to grope another in her sleep; however, he is stopped, and repents of his wrongdoing.
The goddess Bishamonten usually wears a battle outfit consisting of a skimpy bra top and miniskirt.
A group of people all are inspected by a doctor. This involves them disrobing. One woman's full backside is seen. You can see another's under boob. Lastly, a man strips down and twirls around with his robe obscuring his butt and groin (played for laughs).
