Mikan learns that Goshima and the el principal are behind her mom's death. Then the acedemy starts getting attacked by the z group.
We learn that the elp clone is rebelling against the original.. Now all 3 schools are being attacked, and the mid principal's barrier has been destroyed.. Shiki then makes a deal to become the new middle school principal and have a truce with the high school..? I have no idea...
Mikan doesn't care about escaping now, she cares more about saving the school.. Shiki accepts the deal and restores the barrier, but in exchange he has to agree to give mikan to elementary principal..
