Okay, so after editting a couple of pages, I've come across a regularly occuring thing.
If a character is predominately in a series (ie, Saki, Achiga, or Shinohayu), then their "plot" will consist of that, and then they will be mentioned if they're in other series after their main series. It actually kinda looks messy because of the now overlapping timestreams, there's repetitive information.
Personally, I think there should just be a regular "plot" overview with no descrimination of which series it appeared in. In this way, the plot comes in chronological order to the character, not us. Does this seem alright?
