The female Munakata (宗方) sibling is a secondary antagonist in the adult manga story "Chokugeki Spy S" (直撃スパイS), publishing in the manga of the same name by author Kenji Yamamoto.
The Munakata siblings are hired to guard a seventeen year old girl named Mayu Nonohara. When two men in black approach Mayu, the sister shoots each of them in the head and then has sexual intercourse with her brother.
Sometime later, a team of four cyborg mercenaries appear with intentions of kidnapping Mayu. The sister engages with the smallest of the four; a young boy who goes by the name "Number Two". After wounding his shoulder with her gun, the sister proceeds to rape the boy, despite his protests. This soon turns out to be a bad decision by the villainess, however, as his male member -which is a prosthetic - detaches from his body and gets stuck in her vagina. The sister manages to pull it out just in time for Two to activate a command from the device on his wrist, which causes the member to explode.
The sister, now with her right arm missing, shows up soon after to face off against the mercenary leader, E-137. As Two is no longer seen in the story, it is possible that she ended up killing him after her dismemberment. The sister shoots E-137 with her gun, but because bullets do not affect him, he counters with an attack of his own, rendering her to nothing but a charred corpse.
