Mei Ling appears solely in Episode 5 of the *Demon Beast Invasion* OVA series. She is a Chinese girl on the run from pursuers linked to the Pearl River Triad, fleeing to seek refuge in Hong Kong. During her escape, she crosses paths with G7, an operative for the Interplanetary Mutual Observation Agency. G7's mission is to disrupt the Triad's attempts to form an alliance with the Hybrid—a key series antagonist resulting from a human-demon beast union. The available material does not elaborate on Mei Ling's background or specific motivations for evading the Triad. Her documented role is limited to this single episode, with no further appearances, development, or backstory provided in other episodes, the *Demon Beast Resurrection* OVA, or related franchise media.
