What happens in this episode

Episode 20, Venom’s Flame, uses the series’ central contrast: Sousuke approaches the situation like a soldier, while Kaname and the school setting force him to respond to emotional and civilian consequences as well as tactical ones. Based on the available episode record, the key movement is: The De Danaan is heading toward Melida Island when it receives an emergency contact. Gauron’s troops have appeared at Beridaobu Island! This island is the US military’s chemical weapons base. They have Gauron’s new AS, Venom, rampaging around and also the latest mass production model, known as Shadow. Things start to get tense for Sousuke and the others.

The important PopRot read is that the episode is not disposable even when it leans comedic. It either develops the Sousuke/Kaname dynamic, shows how Mithril operates around Kaname, or tightens the pressure around enemies who know more about the Whispered and Arm Slave technology than ordinary students ever should.
