Tsukiyo plans to get revenge on the heroine Tamayo after learning that her grandfather is planning to leave his entire estate to her when he passes on. She decides to kill Tamayo; an action which she wished she had done long ago, as her grandmother was her grandfather's wife, whereas Tamayo's was simply a servant woman.
Tsukiyo leans that Tamayo is being protected by three butler-droids, one of which she finds very attractive. She has one of her minions hack into the androids programming so that they will obey only her, however, it only ends up affecting two of them, Suketomo and Suketake. Tsukiyo orders the former to serve a poison dish to her bastard relative, but the third butlerdroid, Sukekiyo, detects it in the nick of time. The villainess next orders the other two androids to kill Tamayo by force, but they fail thanks to the Sukekiyo's invention. Tsukiyo decapitates Suketake and then takes Suketomo back to her residence as a consolation, where she then greedily violates him.
Tsukino later abducts Tamayo with the help of her faithful right-hand, Azami, but Sukekiyo goes to rescue her soon after. The villainess and butlerdroid have a showdown within Tsukino's swimming pool, but when she moves to decapitate him with her katanas, she is electrocuted with such force that it strips the flesh from her body, leaving only a skeleton.
