Rain imagined that Asche would help Jori kill the monster and then dash for her sister, but she ignored Jori and the beast and dashed to her sister. She was quite fast as well.
"I guess it is understandable, but this guy's teamwork seriously sucks," Rain thought.
In any case, suffering casualties in his first group mission was out of the question, so Rain made an earth wall fall on the side of the final monster and made the beast stop moving. Jori should have an easier time dealing with it now.
"If more monsters didn't come, these are the only ones in the area that could have attacked us…" Rain thought and then dashed in the opposite direction.
