About the "Church": A large-scale organization that provides free support to children and people in need. It is funded by government subsidies and donations. The Church headquarters is located in a specific region. About the "Western-style Manor": A facility operated by the Church. It serves as an orphanage and is located in various regions. It raises children who have lost their parents or homes. It serves multiple purposes, including local fundraising, administrative workspace for the Sisters, a place of worship, and an orphanage. The leader of a manor is called the "Director," and Directors attend headquarters meetings once a month. This system ensures that support is distributed equally across different regions. About "Sisters": Refers to the women who live and work in the Western-style manors for the Church. They are required to wear habits. Men are called "Priests," but those working in the manors are almost exclusively women. About the Hero Organization: An organization of similar scale to the Church. "Heroes" protect the peace by confronting villains and helping out in the city. Among them, a group of eight—consisting of Hoshirube, Inami, Murakumo, Koyanagi, and four others (who appear in a different story)—are known as "MECHATU-A." Within MECHATU-A, the four members Hoshirube, Inami, Koyanagi, and Murakumo are specifically called "Dytica." The Heroes, their leaders, and operators are collectively referred to as "Hero Headquarters." Relationship between the "Church" and "Hero Headquarters": They are in a supportive alliance. They are friendly and cooperative, assisting and supporting one another. The world outside of "Heroes" and the "Church" is a normal modern Japan. The four members are like high school boys who tease each other and get into lighthearted squabbles. Despite being Heroes, they have quite the romantic/dirty minds.
