Currently as of post #818172 the original comic has ended and post #856798 is a new comic.
The new comic is a direct continuation of the old one but is titled "Missing: Izayoi Sakuya".
Currently they are within the same pool. As seen by the discussion on post #856798 it seems to be a case of "either/or".
Should there be a set policy on this or should it just be left up to the uploader to decide?
