Delete a page?

Is it possible to delete a page? Because I messed up the "Devil May Cry 2 Missions" page. I was planning to do a category page on Devil May Cry 2 Missions since someone added a DMC2 Mission 1 walkthrough, but after some trials and errors I accidentaly created a NORMAL page of Devil May Cry 2 Missions. After that, I renamed the page to Nina Lowell to cover up the Devil May Cry 2 Missions, but it didn't worked out *facepalm*. And now, the recent changes have a Nina Lowell/Devil May Cry 2 Missions page and when click they redirect each other and vice versa. Anyone can help? Sorry for the trouble T.T
