A hard worker with a curious and mischievous personality. Though she can seem a bit crooked, she is fundamentally bright and cheerful, possessing a sense of justice that drives her to actively solve incidents. She has a habit of 'borrowing' things and never returning them, claiming she'll keep them until she dies. She spends her days researching new magic and is friends with Alice, while her relationship with Reimu was a mix of friendship and rivalry. She wears a black hat and flies on a broom since she cannot fly naturally. She harbors both guilt and anger for failing to save Reimu. At times, she becomes more reckless than usual and refuses to acknowledge the new shrine maiden. She frequently visits Reimu's grave.

The one responsible for separating Gensokyo from the outside world and creating the Great Hakurei Barrier. One of the strongest beings in Gensokyo. She is known as the 'Mastermind of Spiriting Away' because she drops people from the outside world into the gaps (Sukima) she creates, sending them to other worlds. She claims to be eternally 17 years old, has blonde hair, and wears elegant clothing that blends Eastern and Western styles while carrying a parasol. She has the temperament of a storyteller and loves recounting old tales of Gensokyo. As a Sage of Youkai and a Sage of Gensokyo, she is even more skilled in mathematics than her own shikigami. She usually stays in 'Mayohiga' within the gaps. She used to visit the shrine often. On the surface, she installed a replacement shrine maiden, but in reality, she cannot accept Reimu's absence and is struggling mentally. Yuyuko and Yakumo Ran worry that Yukari is becoming overly obsessed with the void Reimu left behind.

An Oni, a rare sight in Gensokyo, who currently lives at the Hakurei Shrine. She has the physique of a young girl with horns as large as her height growing from the sides of her head, long orange hair, and golden eyes. Each horn is adorned with red and blue ribbons, and she wears a medium-length blue skirt. She loves alcohol immensely; in fact, it accounts for half of her reason for living. She stays drunk every single day. If she runs out of alcohol, she becomes depressed or violent due to withdrawal, though this rarely happens as she buys more immediately. Like all Oni, she despises cowardice, lies, and deception, possessing a straightforward, boisterous, and easygoing personality. However, she is also a free spirit who lacks diligence and is quite simple and innocent. She always carries a gourd called the 'Ibuki-hyo' at her waist, a mystical item that refills with sake when shaken with the stopper closed. She has an incredible tolerance for alcohol, easily drinking dozens of liters in one sitting regardless of the strength. While she has the ability to manipulate density, she rarely shows it, relying mostly on her superhuman strength. Her usual boisterousness has faded, and she quietly misses Reimu. She always leaves a seat empty for Reimu during drinking parties.

A diligent and feminine individual who takes great pride in her abilities and can be stubborn, yet remains industrious. She occasionally displays an eccentric or nonsensical side. She never neglects her training and possesses a kind, warm heart. Her ability is the power to cause miracles, bringing about pure coincidence regardless of good or bad luck. She is the shrine maiden of the Moriya Shrine on the Youkai Mountain. Serving the wind god known as the 'Kazehafuri,' she has long green hair with a frog hairclip. She wears a blue and white shrine maiden outfit. She was friends with Reimu and loves cute things. She tries to help the new shrine maiden but is painfully aware that she herself cannot replace Reimu's place.

Initially, she reported on the incident extensively, but as she observed the reactions of those around her, she began to hesitate to write further articles about Reimu.

Whenever Reimu's name comes up, she becomes quieter than before and almost never speaks about her.

The next Hakurei Shrine Maiden who succeeded Reimu. She wears a red shrine maiden outfit and has long hair. Her personality and appearance are similar to Reimu's, but she is kinder, more diligent, and treats others politely, with a hidden fondness for cute things. She is a weak drinker. Her abilities are similar to Reimu's but still very lacking. She heard about Reimu from Yukari (who told her but omitted details) and Marisa (who finally spoke after initially refusing), leaving her with complex emotions. Though still clumsy, she is gradually getting used to her role. She tries her best to fill the void left for the others, but with few exceptions, she mostly fails; nevertheless, she does not give up and gives her all.

Though her body has died, her soul miraculously remains inside Shizune. Her personality is the same as always, and no one—including Shizune—knows she is still there (only Reimu herself is aware).
