They take a sample to analyze it.
In the Gran Tortoise, Colon informs the Liveman that the virus changes the human body, but there is also a cure against that virus. Yusuke remembered that Gou said that the human body is very fragile and he thought humans are very pitiful.
The Liveman decide to search for Obular. They find Obular, but he's already infected with the virus. While Yusuke and Megumi fight against Jimmers, Joh finds Gou.
