I thought Jin-Woo would just bring out Beru on the first fight but i guess he wanted to gauge her abilities and compare it to some of his higher-ranked shadows.He was considerate of Cha as well and asked her if she was sure if she really wanted to fight Beru because it might actually have left a scar on her mental fortitude after fighting against Beru.Hope to see more chapters soon and thanks for the translations :3
