The V Siren [Neptune] joins the Volks IMS – Injection Assembly Mortar Headd Series as IMS #03, bringing one of the most elegant machines from The Five Star Stories into 1/100 scale model kit form.
Associated with the powerful Fillmore Empire, the V Siren is known for its refined armour layout and high-mobility combat design. Compared with bulkier Mortar Headds, Neptune has a more graceful and streamlined silhouette, giving the finished model a distinctive presence within any FSS collection.
This kit captures the machine’s tall, regal proportions, sharp armour detailing and beautiful blue-and-white colour scheme. The 3-colour moulded parts allow it to display well after assembly, while painting and detail work can further enhance the shoulder crest, armour panels and mechanical sections for a more premium finish.
As part of the Volks IMS range, this is best suited to modellers who enjoy detailed mecha kits with a more traditional model-building feel. It makes an excellent companion piece to other IMS releases such as the BANG, Batsh the Black Knight and V Siren [Prominence].
