Chapter 157

Nanomachine Rescue is the one hundred and fifty-seventh chapter of the Black Cat manga and the eighth chapter of Volume 17.

Plot
Doctor tells Train Heartnet and Eve that they cannot save Mundock and Touma Fudou without killing them, as there is no vaccine for the Berserker. Train however, is adamant on trying. The two controlled sweepers attack. Train tells Eve to wait for his signal before fighting the two. Eve watches the battle while remembering their plan: To send her nanomachines into Mundock and Fudou's system so that they destroy the Doctor's own nanomachines. She remembers Sven Vollfied telling her to be careful and that if she gets hurt or scared, she will run. The girl however, decides to carry on.

After knocking down Mundock, and holding Fudou, Train gives Eve the signal. The girl then attaches her hair to both men's foreheads and sends her nanomachines into their systems to fight off the Doctor's nanomachines, effectively saving them. Doctor is shocked, but then smiles at the discovery of his new "Ideal" test subject.
