Reynard

He is incredibly jealous of Dillon's double barrier crystallizing talent. General Soldier of Team 0-13.

Reynard Parsol possible backstory - Reynard fakes being an indifferent and innocent business owner, but he's known to be ambitious and a bit on the ruthless side. He had no qualms about accepting Luna Bolche's friends' plot to ruin her family name and shutting down their business in return for some side benefits. He plays the villain mostly because it's easier to make a name for himself that way, and hopes to draw out the enemies who abducted his sister and childhood friend more than eight years ago. They have been missing ever since. Make him Luna's love interest (possibly) in a surprising turn of events when he's thought of as the villain in the story?
