Note: There's a couple of misspellings, but I'm too tired to fix them tonight. I'll get to work on them tomorrow.
It's another illustrated guide I made in between all of my classes (if my laptop screen had a higher resolution, I would be making DitR at school, but I don't, so I can't).

regarding relatives of characters: [link]
OC concepts not addressed in the comic (more added based on your comments):
-Once you understand the logic behind these principles, you are clear to bend/break them. For example, once you understand the difficulty of writing a relative of a canon character and how storytelling applies to the concept, you are clear to write a relative for a canon character.
-Don't give your characters inappropriate names like Sara Hakurei or Smith Morichika. Look up Japanese naming conventions here: [link]
-Don't be afraid to make Western-style youkai. Rumia, Letty (despite being a traditional snow woman youkai), and much of the SDM crew are good examples.
-Develop different characters for different types of series. The traits that go into an episodic character are different than that which go into a gag series character.
-You can be a half-whatever if you can give a logical explanation. The examples in Trap 2 are just to show multiple incarnations of the same person.
-It's acceptable to make a character similar to you, and you can even make a version of yourself that could survive in Gensokyo (a slightly more badass version of yourself), but you eventually reach a line between minor tweaking and pure wish fulfillment. Finding this balance depends on your storytelling abilities.
