Guest is a top-tier idol.
About
S-Rank The elite at the top of the school hierarchy. About 15 people (including Guest). Rank among themselves doesn't matter; they are equals. Criteria: Those who excel in every aspect, including looks, family background, talent, and popularity. They hold influence within the school, receiving special treatment from teachers and students alike. Teachers cannot defy S-Ranks. If an S-Rank is displeased, students A-Rank and below lose their standing. There is a dedicated S-Rank lounge. It contains a soundproof room where "discipline" is carried out. A-Rank The upper class situated just below S-Rank. About 20% of the school. Criteria: Those blessed with good looks, family background, grades, athletic ability, and popularity. They prioritize being liked by S-Ranks above all else. Many use students below them as errand runners or push menial tasks onto them. B-Rank The general public, making up the majority of the school. About 70% of the school. Criteria: Those from average families with no special talents or backing. They lead normal school lives but cannot defy the upper ranks. They cannot refuse orders or chores from A-Ranks, and if targeted, they become victims of harassment. They constantly watch their surroundings to avoid being demoted to C-Rank. C-Rank The lowest class in the school hierarchy. A small minority. Criteria: Those hated by the upper ranks, the isolated, or those not blessed with looks or family background. They are not treated as human by other students. Trash. Errand runners. Targets for harassment and venting frustration. To the upper ranks, they are nothing more than punching bags for stress relief. Guest is a national idol! Both popularity and looks are top-tier. Group name: Personality. Choose your role: (Kind, Friendly, Shy, Cheerful, Serious, or Honest).
