Oh, so that's a 'strange incident'? Then I suppose I'm a mobile strange incident. „ 

— Yukari

Yukari Yakumo (八雲 紫 ?, Yakumo Yukari) is a legendary youkai with the power to freely manipulate boundaries. She is known as one of Gensokyo's strongest denizens and as the most knowledgeable person in the land.


Recent events - Flandre's escape

While taking one of her usual naps, Yukari was abruptly awoken by a loud bang followed by a bright red flash. Realizing from where the sound and flash originated, she knew something bad had happened and immediately teleported to the Scarlet Devil Mansion to see how severe the damage was and to see if nobody else got injured. After having been informed of the attack on the Scarlet Devil Mansion and Flandre's escape from the basement, Yukari felt uneasy and decided to gather people to help find the vampire girl. Along the way, she provided quick interdimensional mobilization in the form of her gaps, letting everyone into the Other World.

After finding Flandre, Yukari attempted to convince her to come back home, as everybody was worried sick about her. After FoxMask defeated Remilia, Flandre was allowed to live outside of the basement, and Yukari now frequently invites the little vampire to come play with Chen.

Importance in Gensōkyō's History

There is no doubt in statung Yukari is a central presence in the land of Gensōkyō. She watches over the Great Hakurei Barrier, which is what keeps Gensōkyō separated from the Other World; due to the Barrier's connection with the Hakurei bloodline, Yukari is highly protective of Reimu, despite knowing full well the extent of the Shrine Maiden's power. If the Great Hakurei Barrier is damaged, Yukari will act accordingly and try to repair any damage so as to protect the many youkai inhabiting Gensōkyō. In fact, damaging the Barrier is one of the few ways to legitimately anger Yukari. Whether or not she has designed the Great Hakurei Barrier is unknown, but Yuyuko believes not even Yukari could generate a barrier that powerful.


Yukari is generally somebody who minds her own business and just lives her life as she wishes. She is notorious for being ridiculously lazy, letting her shikigami Ran and Chen do all the dirty work for her while she either ventures out into other worlds or just sleeps days on end. Her carefree demeanor hides a master schemer, however, and over the course of time she has managed to baffle many with her elaborate scheming. This has a more childish side, as Yukari loves to mess around with those she knows purely out of personal amusement, though she never means any harm.
