This episode really touched my heart. The androids from KNoCC decide to investigate the case of the man who fell into the blast furnace, as they're concerned that the incident has intensified the violence of anti-robot factions. They arrive at the factory and interact with the remaining robots, and while I don't want to give away any spoilers, the Ritz No. 9 robots are the most adorable things I've ever seen. We also learn a bit more about their connection to the victim. This episode ends on a very tense note, and while I should be angry again because this anime keeps portraying humans acting ridiculously irrational and violently towards robots... it's police brutality, which is a real thing. I have to say that, animation-wise, the androids' swaying movements while they were singing looked quite ridiculous; there was a noticeable drop in quality, especially considering it was such an emotional moment.
