Using the development data from the STH-05 Hyakuren and STH-14s Hyakuri, Teiwaz is currently developing the Hekija as their successor. A new generation, mass production model with high performance, the Hekija required more time to develop compared to the STH-16 Shiden, for which the mass production system was already set up. Currently, they are the stage of collecting data through limited test machines, and development is progressing smoothly. The Hekija's concept is based on balancing the high mobility of the Hyakuri with the high output level of the Hyakuren. Its frame is based on a modified version of the Teiwaz Frame that is still unnamed due to Hekija's trial status. Like the Shiden, the Hekija's frame is purely Teiwaz-made, from the crafting of the component metals to design and assembly, except for the Ahab Reactor.
