Kei really got attached to Hirasawa in the end. He’s just breaking down under all the pressure he has had on him, turning his character from his earlier self into a more human version of himself. We even get a glimpse of Sato’s background, with his true name and all. The fights between humans and Ajins are really unbalanced; it’s almost like the Ajins are an infinite number of soldiers against the limited number of humans. I wonder what’s going to happen with Kei.
