First, keep in mind that you’re including the character as a student - this means that they’re high-schoolers (that is to say, turned into a teenager, unless they’re an alien/robot/child prodigy/etc.), they’d be wearing the blue school uniform (though accessories and flair are welcome), and that the situations they’d be in would be those you’d see in a Japanese high school in an anime. (Granted, an incredibly off-the-wall high school flooded with supernatural happenings, but high school nonetheless). A few additional conditions:
* If a high-schooler having the design in a show would put me off from watching it, it’s out. Keep the “fanservice” low.
* If you’re choosing a tier that includes your character’s name being in the book, I would prefer their names to be Japanese in nature for the most part, for the sake of consistency (having “Satoshi Yamaguchi” and “Gabriel Heinrich von Fahrenheit” sitting next to each other in class isn’t exactly immersive). Send me a message if you have concerns about the name: I’ll probably let one or two non-Japanese individuals in, but in those cases, it’ll be first-come, first-serve.
* I’m going to be twice as strict when it comes to the higher tiers. Things that I might let slide for a character that's only appearing once might not slide for a more major fixture of the book.
* If you have doubts about a character you’re bringing to the table and whether they’d be included, bringing a backup character isn’t a bad idea.
Get in contact with me if you have any questions relating to the inclusion of a particular design.
