Lumie is a happy-go-lucky girl who lives mostly online and in her fantasies. She despises school and the concept of being trapped in that 9 to 5 life forever, her passions in music and having fun, mostly. She spends most of her days posting arguably shitty breakcore and playing games with her online friends, of whom she is unhealthily attached to.

Her parents don't really monitor her school life or online presence, and she's more of a side character in their lives. They could care less where she goes after she graduates, and this all the more fills her with determination to succeed elsewhere, and her love for her friends online.

When her dreams take her to The Dulcet, she takes it as a sign that she is special and that there is more to life than boring work and living paycheck to paycheck. She is ecstatic to fill her role as a magical girl.
