on pixiv,this has "陰陽鉄"="Iron of Ying and Yang"tag. It is a scene from the new episode. just my opinion,but uploader should mention,or at least check the tag. this confuse people who dont watch on nico.
I made "iron_of_ying&yang" tag,experimentally. add this tag,if there is "陰陽鉄"or"東方陰陽鉄"tag on pixiv. (if it has problem,please tell me)
there are many pictures which is based on iron of y&y. by adding this tag, people can tell the relation to it. and people who hate this crossover can avoid to see them.
on the other hand, adding this tag may give bad impression to get approval.
Also, I think it's probably high time there was an Iron of Yin & Yang tag. It's fairly prevalent. I'll test the waters in the forum to see what others think.
