The White Heron Cup is an annual competition between students of the three houses of the Officers Academy. Byleth is asked to optionally select a student from their chosen house to participate in the competition. Victory in the competition is determined by the competitor's Charm stat, and Byleth is granted one opportunity to put the competing student through a training session that will grant the student a permanent Charm boost. All student characters, including the three house leaders and Flayn are eligible to enter the competition. Should the student Byleth selects for the competition win, they will gain the ability to reclass into a Dancer at any time. In addition, winning the tournament permanently teaches the student the Skill Sword Avo +20, and the Combat Art Sword Dance.
