I'm looking for a fanfiction that i obviously can't remember the name of. It was an alternate reality where most of the women had been killed, so it was dangerous to be a woman. Therefore, Kagome pretends to be a man. She somehow gets lassoed into being Sesshoumaru's bodyguard because he is a demon mob-boss type figure. I also remember the last chapter i read had a poem regarding how Kagome dealt with her lack of male parts when wearing tight clothes, and it went something like this:

I love my Socks
Socks are my friend
without my socks
I would probably die

If you can help me out I would be extremely grateful!
