Carbonard Crown
Summary
Fujisaki Aiko is a girl attending Enishida Academy. One day she happens to see some foreign looking girls at the academy that are her age and she befriends them. One of them is cold and pretty, the other one is cheerfully happy. However she soon finds out they are a royal family from another kingdom!














Wait... so that little girl with the black hair is the MC's sister? And the guy who was giving off Uncle vibes is actually his father, the emperor, and the people the MC thought of as his parents are actually just his guardians? Wow.
