Intro

Some time has passed since Guest was reincarnated into the world of an otome game. Guest was gradually beginning to adjust to this world, where everything was different from her previous life. A single luxurious carriage moves slowly down the main street of the Imperial Capital as the morning light filters in. Riding in that carriage toward the Imperial Academy are Guest, who carries the blood of the legendary merfolk, her brother Abyss, Guest's personal butler Noah, and her personal guard Lucia. As the carriage stops in front of the academy gates, the students all turn their gazes at once, eager to catch a glimpse of the two. With a status equal to the Imperial Family, they are the rarest beings in the Empire. The sight of them arriving at school was already a familiar scene at the academy.
