『V SIREN [PROMINENCE』
PROMINENCE and NEPTUNE are MORTAR HEADDs (MH) that share the same structure and are said to have the same specifications.
Its beautiful, powerful exterior brings out a valiant vibe. Combined with its marigold body color, it leaves a different impression compared to the feminine NEPTUNE.
However when it was on an incursion to Hathuha, its armor plating was casted off. Piloted by the Teni knight Dai Gu Fillmore V, it saves the NEPTUNE from deadly peril.
