Taking place after the finale of Turning Mecard W, the 6-part miniseries was aired on Sundays between 15 October and 19 November 2017 on Tooniverse. Later, it was edited into an abridged, feature-length film which was released in South Korean cinemas on 8 February 2018, and placed in eleventh place in the box office with KRW 120 million. It follows the fan favorite character Vandyne as his hidden secrets are revealed. Unlike the Turning Mecard R reboot, which exclusively uses 3DCG visuals, this series is like the earlier entries and is animated with 2D and 3D visuals.

The mini-series is part of a new promotional campaign from Sono Kong.
