Age: 16
Girlfriend no. 20
Granddaughter of the previous Head Maid of the Hanazono family aspires to become a professional maid, following the example of her beloved "big sister" Mei. She held a grudge toward Rentarou, thinking he was going to steal Mei from her... Then she became a girlfriend herself, turning into some kind of sis-co shoujo filter tsundere.
Mai and Mei are not blood related, even if they share the same pun last name: "Meido"; since it is written with different kanjis.
