Sudo asks Aiko to destroy the two together, as to kill Nana would hurt him and to leave Nana would mean in his being devoured, but she pulls him out of Nana, telling him to live.
Sudo requests that Aiko eliminate the two together, arguing that harming Nana would harm him, while abandoning her would result in his demise. However, Aiko removes Sudo from Nana and encourages him to survive.
