Nyotengu is a princess of the tengu realm who first appeared in a 2014 update version of Dead or Alive 5 Ultimate Arcade.
Details of her life are unclear, other than that she apparently existed as early as the Heian Era of Japan. She was also instrumental in causing a week-long typhoon in the capital due to wanting to alleviate the heat, and apparently observed a particularly ambitious warlord known as Lord Fool. She apparently was also childhood friends with an oni named Kanna, or at least, that's what she believed.
