I can't find shin hisako in shadow lords

I can’t find her is it a mission or something random?

I tried on challenging difficulty, it showed up for me. I guess it takes time for her to show up.

From what I’ve read it’s just one of those cases where if you fight the real one and beat her and she wants to join your team. I played about 50 turns last night and I never got that mission. Hoping to get it tonight so I can finally use her. :slight_smile:
