For a second there, I thought we were looking at another Angelic Layer series. Like that series, this one sees an action figure come to life, but in this series, it's actual life, and her owner is an otaku and not a girl looking for her mother. A Hikaru Vs. Nona argument could be made, and I couldn't decide on it. But I digress! Let's take a look at the PV for this adorable 'toys to life' anime Chou Kadou Girl ⅙: Amazing Stranger.
The summary is as follows:
Bouida Haruto, a hardcore otaku with no interest in 3D (real) women, once appreciated figures from afar, accepting that "if you get into them, there's no turning back." However, when Nona, a character he loved from an anime called "Girls→Planetary Investigation" had a figure of her released, he ended up purchasing it. And then that night, the figure of Nona somehow came to life, and a couple-like lifestyle between man and toy began.
If you think we're going soft with this one, please take note of the space bikini Nona is wearing, and the following screen caps.
Now go watch the anime of smol toy girls.
