To-LOVE-Ru OVA Opening AnimationBoobies on Parade!
Did you catch the visual gag? The sixth girl clearly isn't wearing a bra and she's wearing the boy's school uniform. This girl's name is Run and whenever she sneezes her gender changes to male. As a male she's known as Ren. Unlike Ranma 1/2 the two genders have completely different personalities. Obviously Ren was the one that got dressed that day, at some point he sneezed and now Run's walking around without a bra. I thought it was clever.
