Fics like Fauna Remnata

Jaune Arc is just a civilian aboard the Space Colony Vale, hanging over the planet Remnant. An attack on the colony, however, shackles Jaune to a prototype 'hunter' weapon, a massive humanoid machine known as the 'Crocea Mors'. Now the human companion to an AI named Pyrrha, and an accidental pilot, he comes to realize that, whether he likes it or not, he might just be the key to saving human and faunus both from the hostile alien force known as the Grimm.
