Sol Trigger

Souls give the Shinki Church great magical powers and allows them to develop their technology. So they send their Makina, massive mechanical beasts prowl the land to hunt the People of the Light.

Sol Trigger, a group of warriors with the golden soul is the last hope of their people. They alone can power great weapons with the ability to destroy the metallic skin of the Makina. But every time they wield it, they are burning away a bit of their lives. The weapons use souls as fuel.

The more the Trigger uses a certain skill, the more powerful it becomes. And the same rule applies to their weapons. And when their soul power diminishes, they have to return to their base to get replenished. However, there is only so much souls each base carries.
