Blood Crawler

There was a man named Shogun Jinsai, who set up an experimental facility called the Garden of Light, where he collected war orphans and used them as test subjects to develop special abilities. He then used them as soldiers.
The Southern Army condemned this inhumane practice, and the Northern Army fought each other time and again,
The children of the Garden of Light were sent to the front. At this time, Lunaflare also joined the war, and many battles were fought along the Veil Line.
This was the case in the Garden of Light, but once there was an escape.
The escapees were Crowe, Rain, Johan and Jeani.
Jeani, however, was captured on his way out.
