Abandoned Pawn of the Stars

The war between humans and the alien Zerg "Star Eaters" has lasted for hundreds of years. The latest discovery: Human pilots can create the most powerful weapon - a "symbiosis machine" by neurally linking it with the remains of alien creatures. But these drivers will gradually have their minds eroded and are regarded as "quasi-monsters". They were sent to the front line to carry out the "lair clearing" without any death, and were called "resonators". The only thing connecting them is a "silent commander" girl from behind who is born unable to resonate but can clearly feel all their pain and loneliness.
