Chapitre 77: Experiment 04.

When Zero Five brought up the topic Sam realized that he hadn't been giving her much attention lately. The most he did was hug her a little after she recovered from her injuries that one time. 

"Do you want to continue the experiment, Five?" 

Five had asked him if he sees her as a human. Using that question as the starting point, Sam convinced the Valkyrie to participate in some lewd acts under the guise of learning about how much the weapons resemble normal humans.

"No, it's just…" fidgeting a little, Five looked at him with upturned eyes and said. "I want to spend some time with Doctor, that's all."

"... I see…"

Sam couldn't help but think how adorable she is. Five was one of the most beautiful women he has ever seen, if he considers Valkyries as humans of course.
