In medieval times it was a tradition to hold a mock battle between forces representing good and evil on All Hallows Eve. At first the evil side would prevail, then at midnight, when it became All Saints Day, the tide would turn for the good forces.
This tradition continues, during the day, at the children's tutorial program. Their headmaster leads the forces of evil, poor guy has to bribe the kids to be on his side since everyone wants to be on the good side.
Kevin J. led the forces of good. He was dressed to be Charles Martel. Alex was a Teutonic knight and Monica was Hildegard of Bingen, the abbess and musician.
