I have always had this thought: Nightraid and Budo (the general) could have worked together, since they both had the same goal: Remove the source of corruption, which was the Minister. Then entrust him to help the royal family to go in the right path.
As for Tatsumi, all he had to do was to take Esdese away with him, hunting danger beasts or whatever for the rest of their lives, while they mated like beasts.
But nope, they dropped the ball with Budo. HARD
