thinking about it, have we seen Nue (or possibly mamizo?) yet? with their transformation abilities, it wouldn't be unheard of that they infiltrated the group and are sabotaging it from the inside.
You know, I just noticed that we haven't seen Marisa's face yet. In all the posts in this series, she's always been facing away from the viewer. Maybe it's a sign (or I'm just thinking too much)?
dont know why everyone confused marisa nad alice were originally fighting as we can see here post #802063 which also explains why she used a master spark here post #1030587
