Mai Meido

Mai Meido is Rentaro's 20th girlfriend from 100 Girlfriends franchise. She is a maid that serves Hahari and is Mei's self-proclaimed younger sister.

Much like her sister's love for Hanazono Hahari, Mai is absolutely dedicated to Mei, often getting lost in thought while admiring her. Her dedication is so strong that she initially resents Rentarou for being a threat that may take Mei away from her.

Unlike Mei, Mai is very clumsy, consistently slipping and tripping over things, although she is often caught by Mei before she can get hurt.
