But that's not even the worst part. Kayoko you can just deal with by resetting, it's simple mechanics of the hand hitting the esc button. The worst part is that during the final moments of phase 1, you need to position your students in a way that Kayoko becomes closer to Tsukuyo than Mika. By letting Mika take 1.5 steps between EX activations. HOWEVER, if you let her make 2 steps - she will be too close and become the off-tank again. And if you let her take only 1 step, she will run forward after the second EX, because she ends up out of range for her normal attacks.
