Henri

Witch class.
The first student in history who's repeating a year at Lilac Academy.
Normally, students are expelled if they're unable to pass their finals, but since Henri is from an especially distinguished family, an exception was made to give her a second chance.
She's cheerful and friendly, and she doesn't sweat the small stuff—a trait typical of witches.
Even though she often fails when casting spells, she never doubts that she'll succeed next time.
While Henri uses her magic with the best intentions, she often accidentally ends up causing headaches for Emil.
