Managed to tag just about every missing character except for the samurai sitting next to Yagyuu

Removing the go and board_game tags. I'm not seeing a go board so I assume it's our perennial autotagging issues with things labled FGO. If you see some go playing, please add it back and I apologize in advance.

If someone's searching for pictures of people playing go, it's disappointing if they have to sift through unrelated (albeit nice) Fate pics.
