context:
when touhou 16 was officially uploaded to steam, several users uploaded their fangames as well.
one of the first was “东方胖次争夺战 TouHou Pants Contest” which stood out for being one of the first touhou games with adult content in Steam.
well, it turns out that the author did not upload the game.
someone uploaded a pirated copy and translated with google translator.
when this came to light, the real author made this fanart.
