Don't Act Spoiled!! - S2.E11

One of Kazuki's subordinates, a vengeful ghost, creates chaos in Japan with flying zombies. The girls attempt to exorcise the zombies by themselves but the task proves too hard. They find Ikkou ballgagged, bound with bondage restraints by Jotoku for dismally failing all his subjects at school. Ikkou awakens and successfully exorcises all the spirit but faints afterwards. Kazuki's jealousy is tangible when she sees Ikkou and Chitose together.
