Farewell, Blue Buster - S1.E21

Finding the Energy Management Center base's air conditioner on the fritz, Hiromu and Yoko find Ryuji overheating before he loses consciousness. After the others get him to the medical ward, having met Masato earlier, Gorisaki frets when told by the man that Ryuji's inclusive medical checkup says he might die the next time he goes berserk. Hiromu and Yoko come up with a plan to save Ryuji before they are deployed to the Nakaya district where they face off against Dumbelloid before they find themselves exercising against their will, allowing the Metaloid to escape. Soon after, after playing the age card, Hiromu convinces Kuroki to make Morishita the new Blue Buster, much to Ryuji's dismay.
