Mei Meido is Rentaro's 8th girlfriend from 100 Girlfriends franchise. She is an all-around maid. It seems that she can do nearly everything (even her eyes closed), including driving, cooking, shooting, and even nursing. Some of her skills are even at the exceptional level, such as she can throw white balls.
Mei is also shown to exceed her already exceptional abilities if ordered to do so by Hahari. This has been likened to casting a buff in a video game.
Mei is polite and proper, rarely showing strong emotions. She is very loyal to Hahari above all else and is unlikely to do anything unless given permission or ordered to by Hahari specifically. Mei's fanatical loyalty to the Rentarou Family and the Hanazono Household results in her gladly offering to "eliminate" people that threaten, insult, or even mildly inconvenience Rentarou, Hahari, or the other girlfriends.
Mei loves that Rentarou makes Hahari happy and helps her accept that it's okay for them to do favors for her. She has shown on several occasions her love for being a dog and acting as one, always faithful and loyal.
