It is the successor model to the "Daughtress" that appeared near the end of the plot.
Thanks to data feedback from the "Gundam Virsago", the Daughtress Neo features a sharp-looking profile on its outer appearance and weapons, both vestiges from the Virsago.This machine didn't have much of a chance to shine during the show, but its design exudes the very essence of a high-spec mass-production model. Which is simply irresistible!
