The Five Pledges

Five Pledges
The Five Pledges for the Demon King Worship are:


 * First, if you become a worshipper, you shall enshrine a statue of the evil god in your room
 * Second, in strict secrecy, you shall strive to spread the word to your friends
 * Third, if you commit a sin, you shall confess to the Demon Kings, and accept their words
 * Fourth, if you confess a sin, you shan't cry even if you’re ignored by the Demon Kings
 * Fifth, you shall lead a normal life every day, and not trouble other people

Trivia

 * It's implied that the "statues of the evil gods" are the figures released by Hobby Japan/Orchid Seed
 * There's a form in the official site to "confess your sins" to the Demon Kings, to which they usually reply
