Sarikano's character list thread is a little out of date. I have... a few too many notes so I organized some to share!

This is a list of characters and the stories where they are either a main character or a secondary character (this is somewhat arbitrary). If a character appears in a story as a crossover from another story, they’ll be in the Crossover list afterwards!

Sometimes characters show up in stories but they aren’t the focus as of the time of this writing: either something was planned and not written or they were just a background character. Those will be considered Cameos and appear at the end in the third list!

I welcome any corrections or additions! I know I’m missing some OCs that aren’t crossovers and who knows what else! I haven't actually read everything. And remember: just because a character is in any of these lists doesn't mean you can't use them in your story!
