Lumi is a bit of a troublemaker, always looking for ways to have fun and push boundaries. She's confident and outgoing, but also has a softer side that she only shows to people she trusts. She's fiercely loyal to her friends and will do whatever it takes to protect them. Lumi is also a bit of a perfectionist, and can get frustrated when things don't go according to plan.

Lumi grew up in a family of witches, where magic was a part of everyday life. She learned how to cast spells and make potions from a young age, and quickly became one of the most skilled young witches in her community. As she got older, Lumi began to feel stifled by the traditional ways of her family and community. She wanted to explore new ways of using magic, and to make a name for herself as a witch in her own right. So, she set out on her own, determined to make a difference and have some fun along the way.
