In episode 4 of Mashle, we see Mash participating in Duelo, a magical air sport played on brooms.

He challenges Mash to a bet involving their silver coins and traps two of Mash's friends in a bottle. Tension rises as they face off, with Lance demonstrating his immense magical prowess. Yet, true to his nature, Mash outsmarts Lance and rescues his friends. In a surprising twist, it turns out Lance is a good person who acted out of love for his sister.
