Frustrated with Yomogi's angst interfering with Dynazenon training, Gauma pushes him to deal with his feelings for Yume -- but when he gets a horrible cold, that only makes things more complicated! But why is Sizumu joining their class, and why is he just wearing his ridiculous Kaiju Eugenicist yacht club outfit there? What super-cool power does this episode's kaiju have? And can they beat it with Yomogi out of action? Join us this week for episode 4 of SSSS.Dynazenon, "What Is This Thumping Heart?"
