When she went from being the center of attention at school to a "criminal", though, she grew more jaded. Mei is a Valkyrie and a Warrior of Light. Her motivation is to protect her loved ones. She is also known as the Queen of Thunder. After meeting Elysia and becoming the Herrscher of Origin, Mei became more calm and laid-back.
