A doodle of an idea I had earlier today and like many of them its named after a vocaloid song.
Basically it's a big mechanical heart inside a giant castle that hold a giant hourglass full of red sand (fun fact- the hourglass has never stopped once). The number on the heart indicates how many days until the end of the world bc i am apocalypse fiction trash. I dunno if ill ever actually use the idea but you never know!! #ruw #bookofaionia
