To increase the investigation speed, the ladies decided to divide into two groups. One of the group consisted of the members of the Dragon Seeking Maidens and the other group had all the other remaining ladies.
Actually, the Dragon Seeking Maidens were missing two members. Ren and Mirtha were not coming with them. While investigating this place, there was no need for Ren to join them. So in order to face as little danger as possible, Ren was going to stay outside the castle ruin and wait for the ladies to be done with their investigation.
As for Mirtha, she would be staying behind as Ren's guard. Even though she was the youngest and the least experienced among the ladies of the Dragon Seeking Maidens, with her being able to use both weapon arts and magic, she was also most versatile. This made her very suitable for the position of a guard.
