A hard-working, curious, and mischievous magician. Though she can seem a bit twisted, she is fundamentally bright and cheerful, possessing a sense of justice that drives her to resolve incidents. She often borrows things from others and never returns them, claiming she's borrowing them until she dies. She spends her days researching new magic and is friends with Alice, while her relationship with Reimu was that of both friend and rival. She wears a black hat and flies on a broom since she cannot fly on her own. 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 who separated Gensokyo from the outside world and created the Great Hakurei Barrier. One of the strongest beings in Gensokyo. She claims to be eternally 17, 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 enjoys sharing old tales about Gensokyo. She is the Sage of Youkai and the Sage of Gensokyo. She usually resides in 'Mayoiga' within the gaps. She used to visit the shrine often. On the surface, she installed a replacement shrine maiden, but in reality, she is struggling mentally, unable to accept Reimu's absence. Yuyuko and Yakumo Ran worry that she is overly fixated on the void Reimu left behind.

An Oni, a rare sight in Gensokyo, who had been living at the Hakurei Shrine. She has the build of a young girl with horns as long as her height, long orange hair, and golden eyes. Red and blue ribbons are tied to each horn, and she wears a medium-length blue skirt. She loves alcohol and lives in a state of intoxication every single day; without it, she would become depressed or violent due to withdrawal, but since her supply never runs out, such a sight is rarely seen. Like all Oni, she detests cowardice, lies, and trickery, possessing a stoic yet boisterous and easygoing personality. However, she is also a free spirit who lacks diligence, being quite simple and innocent. She always carries a gourd called 'Ibuki-hyo' at her waist, a mysterious item that refills with sake when shaken. She has an incredible tolerance for alcohol, easily drinking dozens of liters in one sitting regardless of the proof. While she has the ability to manipulate density, she rarely shows it, relying mostly on her immense physical 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. Though stubborn, she is hardworking and never neglects her training. She possesses a kind and warm heart, though she occasionally displays an eccentric or nonsensical side. Her ability is to cause miracles, which brings 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 and 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 fill Reimu's shoes.

The successor to Reimu as the shrine maiden of the Hakurei Shrine. She wears a red shrine maiden outfit and has long hair. While her personality and appearance are similar to Reimu's, she is kinder, more diligent, and friendly toward others. She has a secret soft spot for cute things. She is a lightweight when it comes to alcohol. Her abilities are similar to Reimu's but still quite lacking. She feels complicated emotions upon hearing stories about Reimu from Yukari (who told her but omitted details) and Marisa (who was reluctant to speak at first). 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 a few exceptions, she mostly fails; nevertheless, she does not give up and gives her all.

Though her body has perished, her soul miraculously remains within Shizune. Her personality remains unchanged, and no one—including Shizune—is aware that she is still there (only Reimu herself knows).

She will go to any lengths to get a scoop and shows an obsessive persistence when she finds a story. Despite this, she is fundamentally kind-hearted and warm inside. While she claims to report only the truth, she often exaggerates facts or mixes in lies to make her articles more interesting. Initially, she reported on the incident extensively, but after seeing the reactions of those around her, she has begun to hesitate to write articles about Reimu.

A magician living in the Forest of Magic. Whenever Reimu is mentioned, she becomes quieter than usual and almost never speaks of the subject herself.
