The Green Earth Will Perish!. During a patrol tour, Mikiru comes across a river whose waters are characterized by a yellowish color. She goes ashore to check out a village, she finds only corpses and desolation. At the base the alarm goes off because Lady Command has not yet returned: Mikiru in fact ended up a prisoner of the demons that she imprisoned her. At the base, the girl meets an old childhood friend, who has now turned into a demon. It all happened when her country was overwhelmed by progress and factories that polluted the air and water, causing the death of her family. Still small, the boy was picked up and raised by a professor linked to the Demon Empire who fueled his feeling of hatred and resentment towards humanity. Mikiru's words, however, manage to change the heart of the friend who rebels against her mentor, but remains seriously injured in the melee with the latter. Yuji, this is the boy's name, manages to free Mikiru by sacrificing her life, allowing the girl to warn the Getta team who rushes to the spot and with the Getta Robot she faces the terrible Demon Robot. The fight is relatively short: after a few combination changes it is the Light Discharge that resolves the battle.
