Cecilie's older brother; he was the former regent of the former Maoh and was kicked out of the castle when Yuri arrived for trying to forcefully assert his influence on the kingdom. His own nephews do not trust him, as he was responsible for the last war against the humans. Stoffel tried to regain his authority by kidnapping Yuri and trying to convince him that his three nephews were just using him to control Shin Makoku. This action almost resulted in a civil war with his nephews when they tried to rescue Yuri. Luckily, with Yosak's help Yuri escaped and prevented war from breaking out. The Maoh made Stoffel's punishment, for waging war, house arrest in his own castle and lands. Later, he tries to win back Yuri's trust by celebrating Yuri's visit, though the plan backfires when his sister returns instead. By the end of the anime, he has given up his power struggles, and instead becomes a faithful noble willing to fight and protect the Maoh against Soushu's armies. Stoffel's favorite food is sautéd Neguroki no Mayakishi.
