Eita Akutsu is a loner & an introverted mecha otaku.
One night, the cheerful and popular gal, Makina Agatsuma, suddenly appears at his apartment. But something seems off about her.
When she abruptly strips in front of him… what he sees is not a human body, but a mechanical one!
It turns out that Makina is an AI love robot designed for intimacy, yet she's been restricted from accessing any adult-related information!
Eita, on the other hand, is a pure-hearted virgin who is extremely awkward with anything lewd.
Thus begins their top-secret cohabitation, where no one must find out her true nature!
A super-cute, high-energy gal—easily the most popular girl in school.
But in reality, she’s an AI robot designed purely for… adult activities.
She keeps her true identity a secret.
A socially awkward, introverted, and lonely mecha nerd who lives alone in a tiny apartment.
By chance, he stumbles upon Makina’s secret and ends up supporting her while they live together.
Makina’s best friend—and the most unhinged fujoshi in existence.
Her wild imagination runs out of control, and she’s convinced that Eita, who helps Makina, is the exact kind of creepy pervert you’d see in the raunchiest doujinshi.
A combat AI robot that appears before Mamimi.
Usually expressionless, but after undergoing Mamimi’s… unique training, she slowly awakens to a whole new kind of "humanity."
The landlady of Eita’s apartment complex. His mother personally asked her to keep an eye on him. For some reason, she’s always giving off a strangely seductive vibe…
A mysterious girl appears before Eita. At first glance, she’s ridiculously cute, pure-hearted, and so fragile that anyone would feel the urge to protect her… but is she really what she seems?
