Majo Vanilla is the witch world's no.1 baker. She is in the senate.
She is the last examiner in Ojamajo Doremi Motto. The Ojamajos had to find and prepare the "recipe of illusion" in order to pass the exam. Momoko had the most difficulties competing against her, since she is actually Monroe's twin sister.
Unlike her sister she seems to be very serious and strict; but she did show a caring side a quite few times.
