While on ANN ( anime news network) looking up information about some anime I was watching and other stuff, I stumbled upon an anime series that is great for those Otaku that also are TB/AB/DL's. The series in question is called Nanaka 6/17.
The story is about a college or Highschool student ( I forget what if he was a college student or not. But that REALLY doesn't matter). Anyways, she get's into a crash accident which, this causes her to revert back to a six year old. I looked it up, and it looks pretty good. The art style is a hybrid of chibi and the normal realistic anime art style.
If you want more information on it, here's the link.
