The single most popular student(s) in school. Beyond that, however, school idols can be a widely varying bunch. Though membership of The Beautiful Elite is generally mandatory, school idols can be academically accomplished (or not), great athletes (or not), or the nicest people you've ever met (or not). While more school idols tend towards being Aces than not, what really only defines this trope is massive in-series popularity; most common symptoms of which include being met with fawning adulation wherever they go, an Instant Fanclub or three, and/or a group of highly jealous and violently protective stalkers.
