Huh, interesting, I wondered why the hero of the south would choose to die at that battle rather than just waiting to team up with Himmel when he arrived. He must have done something at that battle to disrupt the contingency plan of the demons. Maybe created a weakness that wasn't there before and now, the future is up in the air. Since both he and that demon could see the future, what happened then must have been crucial for both sides to win and now, victory depends on if Frieren can piece it together.
