I know 428 refers to the game as a whole while canaan refers to the anime adaptation of the Type Moon segment of the game, which is airing soon.
But then there is also a piece of fanart of the 428 game here on db, post #445031, which was tagged as 428:_fuusasareta_shibuya_de.
So do we just tag everything related to the game as 428, pictures that apply to the anime you also add the tag canaan and those for the game you tag 428:_fuusasareta_shibuya_de?
If that works then, would the following implications be advisable?
canaan ---> 428
428:_fuusasareta_shibuya_de ---> 428
Edit: changed the macrons.
