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
Seriously though can we all agree how friggin' Ballsy it is to not only ask for his strongest summon but doing so knowing EXACTLY who it is? Most people here expected her to be traumatized once she sees him.
