Continuity
         Does not alter the original events but adds new material. (A
         lost episode where the members of Tenchi Muyo go on a hiking
         trip.)

You might want to add a topic like Orginal Flavor that appear's in the 
Ranma 1/2 Fan-fic guide . This topic can be used to cover Fan-fic that 
stray's away from the orginal feel of the sourace material . For example 
, a Drama based on comedy series . 

Ja ne!!
