That looks like the second season of Ikkitousen, the girl doing the kissing is Saji I believe. From what I hear, Saji goes around kissing people to take control of their minds so they will fight for her.
Here's a clip of her and Hakufu

I think there are a few more of her doing it. I can't believe I never noticed that one not being up here.
