I love this show. It just makes me appreciate every little bit of technology that we have today every time I watch. And this episode was quite emotional to boot. Byakuya collected rare elements with everything he's got just for Senku to revive the civilization. And his efforts were not wasted. Senku finally got nitric acid to revive all of humanity starting with of course Kingdom of Science people. I can't wait for October to come and continue watching this show.
