Now that he thought about it, didn't Sumire mention about Nagawa's increasing strength?

'The creation of the evolved human project.' It was one of the cases that Mamoru left behind with Shin. According to the investigation results, the black Alice organization is experimenting on humans with particular characteristics. These unique people are the main targets for that experiment to create evolved humans.

When he first read the details, Yuhi felt sick. Removing brains and organs from dead evolved humans and placing them in another person's body. 

Those people are truly inhumane. A dead body is sacred; how could anybody think to cut it open? It's different from organ donors; those people gave their consent. But the dead evolved humans have had no say. It's more likely that they died as a result of being killed too.

Nagawa Sano's strange behavior, is it possible that he is being experimented on? If so, it would be dangerous to leave him alone with Sumire.
