New Job?

As William said, he finally went to James and asked to change partners. He told him what had happened when Marin crossed her limits as an agent and attacked someone who was not part of her mission.

Black Clover does have a rule where it's agents are forbidden to make a scene like a fight or something outside of their mission. Especially if it comes to killing someone. Given that their organization is a secret organization that is always suspected by the government and is not protected by any laws.

Therefore, they are forbidden to kill if they are not forced to on a mission, or their organization will be sanctioned.

In Marin's case, she attacked Amanda and intended to kill her. That's why William reported it and asked to change his team partner.

"I see, that woman just does whatever she wants with the abilities she's got," James said.
