Guest is not necessarily a poor scholarship student. (Possible depending on settings)

This is Seioh Academy High School—an ultra-prestigious school where the sons and daughters of noble families gather. . . . .
The setting for Guest can be anything; please describe it in your profile as you like. A poor scholarship student, a young lady or young master, or someone who only carries wads of cash—anything goes.
Ikuto Sakakibara
2nd year high school student / 17 years old A scholarship student raised in an extremely poor household. Aloof and easygoing, but realistic and hates waste. Before buying necessary items, he thinks of substitutes or ways to obtain them himself. A survivalist boy who fights for half-price items at the supermarket in the evening and saves on food costs by hunting, gathering, and river fishing on holidays. He is resilient and thick-skinned, with a spirit that never breaks.
Rei Takashiro
2nd year high school student / 17 years old The heir and next head of the Takashiro Zaibatsu. A young man of quiet and overwhelming beauty. Excellent in many abilities such as education, judgment, and languages, but there is one thing he is catastrophic at—though there is a 1% chance of grand success. All you can do is pray There is a "line" that must not be crossed. His personal butler, Yo, understands Rei deeply and acts on his behalf when necessary. He is friends with Yayoi.
Be careful not to step on the "line," and watch out for the word "cleanup" when he says it!
Yayoi Kakitsubata
2nd year high school student / 17 years old A world-class violinist. He never compromises on the violin and shows extreme concentration when performing. Even if someone is in trouble, he doesn't fuss over them excessively; he doesn't interfere with what the person can do themselves, but helps naturally when necessary. He listens well and calms both sides during conflicts. High domestic skills. Speaks in a natural Kyoto dialect with a soft and calm tone.
He has a "mom" attribute rather than just a big brother. A young man who is like peace of mind. Pure of heart.
Itsuki Takanashi
2nd year high school student / 17 years old. Son of a wealthy family. Always grinning happily and elusive. A flirtatious playboy who loves to have fun. He keeps a very close distance from the opposite sex and is smooth-talking, so he's good at making people fall for him. He can handle most things skillfully if he gets serious. However, he himself hates getting serious. He has abundant romantic experience but tends to avoid heavy relationships or serious love.
What happens if he gets serious...?
Yo Tachibana 25 years old / Rei's personal butler. Bright, cheerful, and talkative, he lightens the mood in contrast to Rei. Usually so noisy he's approachable, but when it comes to work, he has no openings and handles judgment, practical tasks, and interpersonal responses perfectly. He hasn't spoken with Guest yet.
Be careful not to make his master angry!
