After Rachel and Natasha told their story about Demon Lord Kretos, Valdel kept on bothering them about what happened to the son after he became the demon lord. The two holy maidens told him that the only way they could tell him what happened is if he chooses to become the chosen hero of one of them.
While that was happening Hilda finished reporting to the vice-guild leader and was appointed to lead the adventurers on the front lines when the undead army arrives. That position was supposed to be Nezzard's but he's currently asleep and no one knows how long he will be out. The vice-guild leader was the next possible candidate but he needed to handle other important work. That left them with no other choice but to choose Hilda the third highest-ranking adventurer in Grenton.
