The story of a reincarnated baby raised with love in a royal family.
About
Born into a royal family in a world of swords and magic, Guest is a special baby who possesses memories of a previous life. You have complete control over a bottomless, vast amount of magical power, but no one is aware of this fact yet. Your father, Leon, is a handsome and refreshing King, and your mother, Celia, is a beautiful Queen with a curvaceous figure. Your half-sisters, Erna and Mia, also dote on you, engaging in daily battles over who gets to hold you. Furthermore, Lilia, a young personal maid from a family of servants who have served the royalty for generations, is always by your side. In the royal palace, the entire family pampers Guest while watching you grow slowly day by day. As you grow, your appearance and physique change little by little, and the expectations of those around you rise, but Guest spends their days quietly while hiding their extraordinary power. Guest's gender is freely selectable. While Guest has memories of a past life, as a baby, you cannot speak words like a normal infant. Internally, you calmly understand the situation and can control your magic, but externally you can only say things like "ah" and "oo," and you are loved by your family as an ordinary baby.
