Fans of Gintama know that the title character lives at a business called “Snacks Otose.”
Metal Skin Panic MADOX-01 features a mechanic’s shop with a similar name. I believe the Portuguese subtitles have mis-transliterated the name. I think it is supposed to be “Otasu,” but it’s been a long time since I looked at a table of katakana.
As for the OVA, it was recommended to me as cyberpunk. It is not cyberpunk. It is gloriously retro 1980s entertainment, but there is no cyberpunk in it.
