How to get otaku girl?

Go out out buy a bunch of tacos, a stick, a big box, and some string. Create a trail of taco leading towards the box held up by the stick. As soon as she enters the area of the box pull the string and capture her.

You just need to be yourself try to talk, and get to know them ask about their likes, and dislikes favorite anime, or character they like most of all you have to be patient with them yes, dating an Otaku could be fun, but you have to understand that otakus can be a bit quiet, and socially awkward

Let's be honest here the best way is to get hit by truck senpai and get isekai'd into a world where you are desirable for once... sad world we live in haha

In my experience, being myself and doing the stereotypical things(getting into better shape, having good hygiene, making them laugh, try to be confident, etc) helped getting me two of my otaku girlfriends. I'm currently looking for another partner after 6 years and I know it's frustrating trying to find somebody when you're lonely. However, like most things in life, good things take time and you've got to be patient to find that special someone. Don't act desperate and don't be willing to settle on somebody that doesn't love you or respect you( voice of experience.) Don't be afraid of rejection and give it your best effort. You strike out this time, no biggie, you tried and you're no worse off than before. Who knows, that certain somebody might find you.
