You won't see a better episode in this anime. The emotional intensity from Kohaku's hug and Suika's look of determination to Senku's first mistakes and greatest praise is hard to find, and thank you for doing everything in the same series. It's so beautiful that the tears keep flowing hours after watching it. You can add the series directly to your favorites, otherwise you can't.
I'm so overwhelmed with emotions that I can't even formulate my thoughts.
