The leader of the Half-Dragon was King Arthur. While training future heroes at the academy, he secretly connected with the demon lords and pulled the strings of conflict. King Arthur insisted that these contradictory actions were necessary for the "work of a hero." Yashiro, who had been cynical until then, exploded with anger. "We're the lowest of the low, but you shouldn't be saying that." For his own sake, and for the sake of his disciples who will live in the future, the hero continues to lie.
