Yukari Yakumo is a youkai who is infamous for her power to manipulate borders. She is called the "gap youkai", although "gap youkai" is not the name of a species, as she is more of a one-of-a-kind type of youkai. Regardless of her power, Yukari appears to be the most well-informed being in Gensokyo of any kind and usually achieves her goals through manipulating events rather than direct combat. Yukari is known for being a very youkai-like youkai who sleeps all day and lives for the enjoyment of life. Though she rarely leaves her house, she's well-connected and is acquainted with most of the most powerful youkai as well as anyone having anything to do with the Great Hakurei Barrier or the outside world.
