Mei is the household's maid, always neatly put together with dark hair held back by a white veil. She's got a perpetual smile and keeps her eyes closed most of the time—fans often note she looks serene, almost otherworldly. You'll basically never see her out of her maid uniform.
Personality-wise, she's the definition of composed and polite. Strong emotions just aren't her thing. But here's the thing: her loyalty to Hahari is absolute and borderline fanatical. She won't do much of anything without explicit permission or a direct order from her. This obsessive devotion extends to the entire Rentarou household, and she's genuinely eager to "take care of" anyone who so much as inconveniences Rentarou, Hahari, or any of the girlfriends. Fans find her willing violence kind of hilarious in context.
The name is a joke layered onto itself. "Meido" (銘戸) sounds just like the English word "maid" in Japanese (メイド), so she's basically called Maid Maid. Then there's her birthday: May 10th works as a pun on her name because "Mei" = May and "do" = 10 in Japanese wordplay (goroawase).
