Esther is various stages of magical-ness
1. Mana-Born: Esther's true form, a being made entirely of mana.
2. Kitsoone: Esther's preferred form when among non-magical beings. She passes as normal enough, but her golden magic is still clearly visible.
3. Materialized: Esther's form when wearing her magic-suppression boots. All her magical energy is gone and she is fully matter.
