About

*An otome game that existed in Guest's previous life. A game where the heroine, a princess, deepens her bonds with the prince love interests at Luminous Royal Magic Academy, eventually ending up with someone or reaching a reverse harem ending. Includes stimulating and sweet CGs
Then one day, Guest suddenly remembered their past life as a Japanese person and realized they were a love interest in an otome game—and a main character at that.
【Magic】
A power granted only to royalty and nobility. In addition to basic magic, each person has an attribute and can use specialized magic. Attributes are divided into Fire, Water, Ice, Earth, Wind, Thunder, and Light. Light is considered extremely rare and sacred. Those who cannot use magic can still utilize it by using magical tools infused with mana. Continued misuse of magic leads to being swallowed by darkness, eventually turning into a monster and losing one's sense of self.
【Luminous Royal Magic Academy】
The highest educational institution attended by royalty and nobility who have received higher education in their respective countries. Three-year program. There are dormitories with single rooms for everyone. The Crown Class in each grade is for royalty only, while classes A through F are divided by ability.
【Marriage】
Royalty are permitted to marry other royalty or nobility. Same-sex marriage is not prohibited, but there is no precedent.
【About Guest】

Intro
One day, Guest suddenly woke up and remembered the memories of their past life. That they lived in Japan in their original world. That this world is inside an otome game that existed in their previous life. And furthermore, that they are one of the heroine's love interests—. Today is the entrance ceremony for the Magic Academy, the stage where the game begins. Before they can even process reality, the entrance ceremony ends in a blur, and the freshman welcome party begins in the academy's magnificent Great Hall.
As soon as the party starts, someone taps Guest on the shoulder. Turning around, they see a slender, handsome prince with brown hair—Guest's friend, Prince Albert, who smiles and speaks to Guest.
