Natori

Natori is the leader of Miko Institute in Yamatai. She is the rumored "Miko of Death", having obtained said title due to the unique power of being able to kill anyone by simply having sex with them. Rance turned out to be the only exception, and on the contrary, upon having sex with her, becomes progressively stronger.

As its leader, Natori is very dedicated to carry out the main objective of the Miko Institute. While she seems to dislike the idea of sacrificing mikos, she also realizes that the ritual is needed to prevent more casualties, in which she cannot object.

Sengoku Rance
After hearing a rumor about Miko Institute's activities from 3G, Rance decides that he should pay a visit to earn a free service he always wanted. Though it doesn't seem to go very smoothly when he draws the lottery, in which he always loses, much to his anger. It provokes him to the extent that he said he will attack Yamatai. In response to Rance's threat, Natori appears. Having introduced her status as the representative of Miko institute, she asks Rance to leave, in which Rance strongly objects. In order to satisfy him, Natori gives in, she allows Rance to have the same service given to those who won, though she won't be the one who provides said service to him.

Natori claimed that she doesn't give the service anymore due to being old, which in actuality is a lie to cover her real identity as the Miko of Death, one who is able to kill anybody by simply having a sexual intercourse. Remaining oblivious to the fact, Rance declares war against Miko Institute, so he can H Natori.

Natori will be automatically captured After Oda conquers Miko Institute. She will join under one condition, Rance must allow her to return to Miko Institute from time to time, so that she can help and teach the new representative of Miko Institute, implying that Orochi is still her main concern.

When Rance introduces her to Tamagushi Fuuka, Natori is shocked, as she seems to know her, but she remains silent as she is not really sure with it. Later in the story, Rance asks Natori to open the seal through Orochi's dungeon, confident that he will finish Orochi once and for all. It's soon revealed on the last floor that Fuuka was related to Miko Institute as she was one of the sacrificed mikos in the past, proving Natori's initial thought as right.

In the epilogue, Natori made a brief appearance, she is the first to recognize Isoroku's pregnancy.
