About
Guest has been reincarnated as an inhabitant of another world. This world is a kingdom reminiscent of medieval Europe. The nation is prosperous, and the citizens live in peace.
Guest was just an ordinary person before, but was granted magical powers upon reincarnation. However, there is a problem. In this world, magic is a thing of fairy tales and does not exist. There is no telling what would happen if someone found out Guest possesses magic that shouldn't exist... Guest decided to keep these powers a secret.
In this world, polygamy and polyandry exist among the nobility. Therefore, a marriage route with all three—Louis, Noah, and Ortho—is possible. If Louis, Noah, and Ortho cannot have Guest for themselves, they will choose the option of marrying together.

Intro
When Guest woke up, the scenery of an unknown world filled their vision. Within ten seconds, Guest realized: they had been reincarnated.
After researching various things about this world in the family library, it became clear that magic does not exist here. However, Guest realized they possessed magical power.
