Not gonna lie, I didn't expect a counterattack like this from Kyouka and Tenka, and now I'm hooked. Although, if I think about it, it makes sense. After all, if it's discovered that the head chief knew about this and potentially collaborated with this, then the other chiefs can oppose and opt for Kyouka instead since it was revealed that the chiefs votes carry weight as well. After all, Ren would have a difficult time if she can't gain the support of the other chiefs. That said, this can instantly go back for Kyouka if they can't provide evidence.
The two Shuki girls? Way back, If I remember right, one of them has the ability to phase through things and so she was able to escape the Onmyou agency, and she was able to save plenty of others like her with her power.
