Some images aren't working right now for some reason. Sorry about that!

Welcome to the Demon Castle Database!

My goal is to create a comprehensive database for everything related to the "Sleepy Princess in the Demon Castle" franchise!

Main Characters

About Submissions

I've created a page for anyone who wishes to make sugesstions or fill in missing information.

Fill out this form in order to make a submission, and click here to view the state of your request

I enter requests manually when I'm awake, check back in a day if you don't see your info entered.

I plan on collecting as much information as possible on my own, but I have blindspots. I can't read japanese, I have limited time, and I might simply misunderstand something or miss information while re-reading and re-watching the series. If you notice any missing, incorrect/misleading information, or bugs, feel free to make a submission to the form.

I have no plans to make this a wiki that can be freely edited, I do not have the time, patience, or technical knowhow to create and moderate a proper wiki.
