Bandai adds the VF-31J Siegfried piloted by Hayate Immelman from "Macross Delta" to their HG (High Grade) model kit series. This kit combines high quality and ease of assembly with three-stage interchangeable transformation and the first insert molding in the lineup.

This kit uses three-stage interchangeable transformation to simplify the transformation sequence by using some interchangeable parts. This realizes the ease of assembly, wide range of motion, and refined form that are unique to the HG series. By incorporating interchangeable parts as part of the transformation mechanism, the transformation sequence has been simplified; it easily transforms into its Battroid, Gerwalk, and Fighter stages. A new dimension of mobility has been achieved by eliminating complex structures and providing optimal movable points that are conscious of posing.

This kit features the first insert molding in the HG plastic model series. Parts with complex color coding are reproduced in a simple way by separating the parts, achieving both high quality and ease of assembly. The container unit can be recreated in its stored state by replacing parts. The minigun pod can be deployed forward with a movable axis. Two knives, two pilot figures, a Freyja Wion figure, and a multi-drone base are included. Expressive hand parts are also included to allow for a variety of poses. The canopy uses polarized molding, and it can be opened and closed.

Includes:

• Knives (x2)
• Landing gear (x1 set)
• Parts for recreating fighter form (x1 set)
• Joint part
• Hand parts (x1 set)
• Figures (x3)
• Base for figures
• Stickers

High Grade kits are the most common, have the largest selection, are cost-effective, and beginner-friendly. Size varies, but High Grades are typically around 12 to 15 centimeters tall. If you are new to Gunpla or prefer a more casual build, High Grades are a great choice. High Grades are usually 1/144 scale.
