Yukari is known for being a very Youkai-like Youkai who sleeps all day and lives for the enjoyment of life. She is without a doubt one of the most powerful characters of the Touhou series, but prefers to achieve her goals through manipulating events and people rather than fighting directly. She is the mistress of Ran Yakumo, and is sometimes referred to as the "Gap Youkai".

Yukari seems to be the most well informed being of Gensokyo of any kind. She debuts as the phantasm stage in Perfect Cherry Blossom with Ran Yakumo serving her as a shikigami. Despite being a high-class boss in comparison to other extra and final stage bosses, she has made some appearances in later games

She is known for being one of the oldest and strongest Youkai in all of Gensokyo, as well as one of the wisest.

Youkai (妖怪, "mystic apparition" or "mysterious calamity"), refers to Japanese folk creatures and ghosts, or in general, supernatural beings. There is an endless variety of youkai thanks to the countless stories of such beings across the world. Anything can become a youkai, even ordinary objects and animals and normal humans, an example being Alice.

They are mainly spiritual rather than physical beings, making them more vulnerable to attacks based on faith, such as charms and words, than they are to physical injuries and status ailments. Many youkai are much stronger and longer lived than humans are. However, unlike fairies, they are not immortal.

Boundary Manipulation: Yukari is able to manipulate any boundary, be it material, spiritual, conceptual, metaphysical, and so on so forth. Most commonly, Yukari uses this power by opening gaps, which essentially serve as a portal between two places, and she can choose whether or not only her can pass through, or anything.

Because everything in existence is defined by it's boundaries, there is no limit to the possibilities of this power. Yukari explains in her monologue in A Beautiful Flower Blooming Violet Every Sixty Years that this ability allows her to control the boundaries between any and all things, such as Gensokyo and the Outside World, the worlds of the living and the dead, and even day and night.

Yukari is often stated to be capable of manipulating the boundary between any and all things, however this is questionable, due to known exceptions, such as not being able to create a gap to the moon until very specific circumstances were met.

Onmyoudou: Yukari is skilled in the Taoism derived arts of Onmyoudou, used by traditional Japanese court wizards, and specializing in spells which create and manipulate barriers.

  • Manipulation of Shikigami: Manipulating Shikigami can also be considered another ability of Yukari's. Shikigami is the term used for the summoned spirits of an onmyouji. They are used to protect and serve their master, much like a witch's familiar. They often share a special link to their masters.
  • Barrier Creation and Manipulation: Onmyouji sorcerers are capable of creating and manipulating barriers

Regeneration: Most youkai are able to regenerate from injuries, and it is said that they can recover even from being cut into pieces, if this damage has insufficient "meaning" behind it.

Longevity: Yukari possesses an immensely long lifespan, making her seemingly immortal.

Mind Manipulation: Yukari is able to replace somebody's mind, but it is not known whether or not this is useful for combat.

Teleportation: Through her Boundary Manipulation, she can teleport.

Flight: Yukari is able to fly.


(弾幕) Japanese for "Bullet Curtain", or "Curtain Fire", and also known as "Bullet Hell", Danmaku is the ability to produce a great number of projectiles at once or in quick succession, in order to overwhelm the opponent by the sheer number of them. Dodging Danmaku is notoriously difficult. According to ZUN however, in the Touhou games, when Danmaku fights do happen, they use it much more as a play fight, rather than going all out. Additionally, ZUN has stated that if the characters truly wanted to kill, a ratio of 10:1 bullets would not be necessary.

However, Danmaku can still easily destroy structures and devastate the environment.
