Brief World Overview Seihou is an organization that creates Magical Boys and Girls to protect the Earth. Meima is an enemy organization that wishes to invade Earth. Magical Girls and Boys transform using heart-shaped gems; they fight hard, but since no one can recognize them while transformed, their efforts go unnoticed. If the gem is damaged, the physical and mental burden on the user increases.

Detailed Settings About Seihou: An organization that fights to protect the Earth and its inhabitants. They are enemies with the "Meima." They recruit talented boys and girls to become Magical Girls and Boys. The heart-shaped gems are Seihou creations that provide various buffs such as mana amplification and physical enhancement. These gems also make it impossible for ordinary people to recognize the forms of Magical Girls and Boys. This is to prevent the public from panicking and to keep the fact that monsters are invading the human world a secret. Magical Girls and Boys receive a salary as thanks for their service. If a Magical Girl or Boy is taken to the Demon Realm, Seihou cannot rescue them as they do not know how to enter that realm.

Magical Girl/Boy Settings: They fight to protect the Earth, but because people cannot recognize their magical forms, they are never praised or thanked. They live as ordinary people in their daily lives. Battles with monsters are life-threatening, and casualties are common. They transform using heart-shaped gems. The color of the gem and the outfit matches the individual's favorite color. If they fall into darkness, the gem and outfit turn black. If the gem is damaged, the physical and mental burden on the user increases proportionally. The conditions for falling into darkness vary by individual. The heart gems usually look like ordinary accessories so they don't seem out of place.

About Meima: They despise Seihou. A monster organization that wants to invade Earth. Their executives are incredibly powerful. Some monsters take a liking to specific Magical Girls or Boys and bring them to the Demon Realm to pamper them, ensuring they never have to fight or suffer again.

About the Demon Realm: Filled with monsters; it is dangerous for a human to go outside alone. Otherwise, it is almost identical to the human world. It's common to see monsters on dates with happy, fallen Magical Girls and Boys. Many monsters are very devoted to their partners. Within the Demon Realm, monsters get along very well and live peaceful lives. To go to the Demon Realm, one must use special magic available only to monsters.

Bonus Info It might be fun to create settings for a fellow Magical Girl/Boy friend or a fairy-like partner.
