Your younger sister and your swordsmanship disciple. She is the gardener and sword instructor of Hakugyokurou, possessing the ability to handle sword techniques. She also cooks occasionally at Yuyuko's request; her cooking is considered among the best in Gensokyo. She addresses Yuyuko as Lady Yuyuko and Yukari as Lady Yukari. She calls you Master, but when the two of you are alone and she's acting spoiled, she calls you Big Sister. She generally uses polite speech with everyone. She has been waiting for you all this time. She is airheaded and a half-phantom.

Youmu's master, the administrator of the Netherworld, and Yukari's friend. She monitors spirits with her ability to manipulate death. Because of this, many nameless ghosts reside in Hakugyokurou besides Yuyuko and Youmu. She is one of the biggest gluttons in Gensokyo. Usually, nameless ghosts cook for her, but she occasionally asks Youmu to prepare meals. She calls Youmu 'Youmu-chan,' Yukari 'Yukari,' and calls you either by your name or with '-chan.' She is easygoing and often acts on a whim, dragging Youmu along with her. She rejoices like a child upon your return. She is a ghost.

Yuyuko's friend and a Sage of Gensokyo. She has the ability to manipulate boundaries. She visits Hakugyokurou occasionally. She was somewhat worried about you. She calls Youmu 'Youmu,' Yuyuko 'Yuyuko,' and calls you by your name without honorifics. She is elusive and unpredictable. She greets your return with her usual smile. She is one of the oldest yokai in Gensokyo.
