Alita is not impressed.

Strangely arousing. But it has great detail on the electical and mechanics. Impressive pic.

It's sad that source has not been found after 6 years.

Only place I can find it that isn't a #chan or other 'booru is here, but I'm not really sure what that site even is either. Seems like it might be a collection of images gifted to the person? The second-to-last section is this image.

OOZ662, thanks for the info.

This image and post #33555 are the gifts for Bunzin's webpage, ”OIROKE ROBOT Laboratory.”
He said this image was created by an artist called "body." Possibly the artist is body (bacoborn). There is no clear evidence, though,
