Kenbu Zan's Sword and MAILeS Reiki Kai Polearm based on the promo images of the HG 1/72 model kits from the series Kyoukai Senki by Bandai.
Part separation for easy painting and added some small gimmicks compare to the demo
This is just a imitate, by referencing the promo images and by no mean 100% true to the real product.
Scale it to fit your need, using the entire length. 15-18cm should fit most MG gunpla kits.
