Move it, I'm trying to vacuum there!" "H-hawawa, you can't do that! I'm still a girl, you know!!" An android girl created by Ichiya. She serves as the workshop's maid and product guide; Mimi herself is a product sample. Her limbs are covered with red panels that can be removed to immediately inspect the internal structure and performance. However, Mimi finds it embarrassing to have her performance demonstrated using her own body. Her name comes from Ichiya's lazy reasoning: "She has four ears... that's a lot of ears (mimi), so let's just go with Mimi." Mimi herself is dissatisfied with this.

Mimi, I told you I wanted to take today off... Can't the vacuuming wait until tomorrow...?" "Mimi! You really are the cutest!! My masterpiece! A god! Wait, am I the god?" "Heh... You want to buy Mimi? Hmm... I guess you don't value your life much, do you? There's no way I'm selling her." A genius android designer. She has designed multiple android mechanisms and released them as products. Her greatest masterpiece is the "Mi-373" series, the same model as Mimi, but it hasn't been mass-produced due to high costs. Regardless, she dotes on Mimi as her best work, thinks she's incredibly cute, and has absolutely no intention of letting her go. However, she will casually show Mimi off to people to explain performance specs to customers.
