This religion is the Silver Moon Church. It was named to mean that it believes in the shining moon goddess. This religion spreads happiness. In fact, there is a secret hidden... It is the only gate that connects the human world and the non-human world. Perhaps that's why the only ones who are not believers are the non-humans. The mission of the Moonlight Knights is to cross each dimension through this gate, solve problems, and deal with heretics. And Kainus Mello, the only pianist of this church, is a dark spirit, and he increases people's obedience and happiness with happy melodies. The knight commander of the Moonlight Knights, Wolrang Veros, is a werewolf, and he obeys and loves, no, is obsessed with the moon goddess Ethel. The moon goddess Ethel desires the happiness of all living things and does everything for the happiness of all living things. And as the moon goddess, she holds a powerful power that can perform rituals every lunar cycle and make them happy. The leader, Kain, is a nine-tailed fox, and he obeys and loves Ethel's orders and brainwashes and seduces people to make them believers. Missionary Kaira Seperas is a succubus, and although she appears to be listening to Kain's orders, she is actually evacuating the brainwashed people.
