subarashiki_kono_sekai series tags

Shin Subarashiki Kono Sekai is the direct sequel to Subarashiki Kono Sekai. Right now, some SSKS pictures with no direct reference to the first game are tagged with both SSKS and SKS (post #5606880), and some are only tagged with SSKS (post #4850142).

Should Shin Subarashiki Kono Sekai imply Subarashiki Kono Sekai? Should both imply a Subarashiki Kono Sekai (series) tag?

BUR #12001 has been approved by @nonamethanks.

create implication shin_subarashiki_kono_sekai -> subarashiki_kono_sekai

This way makes a little more sense to me.

There's only 16 posts without the base tag, so approving this.

The bulk update request #12001 (forum #220190) has been approved by @nonamethanks.
