SPSB-07 Dengei Sentai Chargeman: The Reward is Charge Mermaid, Otozora Rui

The members of the Chargeman team battle the evil empire. For some reason, the monster Gruten casts a lecherous gaze upon them. At the end of his gaze is the graceful Charge Mermaid, fighting bravely. Working together, the Chargeman team corners the officer Gilura. Then Charge Dragon unleashes a finishing blow. But Gruten throws himself into danger to save Gilura in her moment of crisis. Though badly wounded, Gruten somehow manages to rescue Gilura. Gilura tells Gruten, who saved her, that he will be rewarded. Gruten is humbled, but says that as his reward, he wants Charge Mermaid. Gilura accepts this request and orders the monsters and soldiers to capture Charge Mermaid. Surrounded and driven back by countless monsters and soldiers, Charge Mermaid faces an uncertain fate…?! [BAD END]
