Shiba's group only learned of the incident with Eini's cousin several years later when they were ready to leave for a quest again.
Although the one who died was Eini's cousin, none of them had met her before, so although they were angry to hear what happened, it didn't affect them too personally.
At that moment, Eini's mother was still pursuing that World God, but she had yet to find him.
As a professional criminal, he was really good at avoiding being caught, although he had to admit that no one had been so insistent as Eini's mother.
The huge price for his head also made it difficult for him to travel. He could change his looks, but it was difficult to change his aura for a long time and almost impossible if there were people stronger than him.
His aura was clearly registered when Eini's cousin asked for help, and while fighting, there was no way he could fake it.
Thus, everyone who wanted to hunt him would be able to learn about his aura beforehand.
