Image Songs are done by groups rather than just individuals, and the second series' opening theme has multiple versions of its theme song: one lyrical, one each with spoken lines from each herd, and on final version of the lyrical verse with all the girls singing it at once.

This is lampshaded in a filler chapter involving the quirky but rarely seen 'leftovers', who according to Evangeline are boring and lack sex appeal. Naturally, Negi's group is made of the most popular characters. Most of the class is divided into reasonably logical Cast Herds based on interests: the jocks, the cheerleaders, and dormmates.
Baccano! does this due to having nearly 2 dozen 'main' characters in addition to the countless other Mooks and crooks.Oceania: Australia and New Zealand, but also includes Tonga, Wy, and Hutt River.Far East: Vietnam, Taiwan, Hong Kong, South Korea and Macau.Benelux: Belgium and Netherlands, but Luxembourg gets mentioned a lot but never really appears.
Mediterranean: Greece, Egypt, and Turkey.Recently extended to Kugelmugel, Molossia, Hutt River, and Ladonia. Micronations: Sealand, Wy, and Seborga.Former USSR: The Baltics + Ukraine and Belarus.Nordics: Sweden, Finland, Denmark, Norway and Iceland.Germanics: Germany, Austria, Prussia, Liechtenstein and Switzerland.Allies: Russia, France, China, England and America.Since all the characters are the embodiments of countries, each Cast Herd is usually built around or named after a shared geographical, historical or cultural element, which often vary based upon what time period is being shown and/or what topic is being discussed. See also Geodesic Cast which repeats the structure of the main character's group and Planet of Hats when this is done with entire worlds/species. Shows which allow for the format of a literal team will always use this trope.

Only a Cast Herd's spokesman would probably appear in the Non-Serial Movie or OAV. If you can't quite tell who the spokesman of a Cast Herd is, imagine it in terms of screentime value. This can be really obvious when you notice that with the exception of perhaps the main Cast Herd, all the others Herd Leaders only talk to their own herd, or other Herd Leaders A huge amount of the people are never given casual conversation. This allows for enough characterization, because we always see them together and that's enough net personality for characters whose physical descriptions are probably longer than those of their personalities. The best solution is to split the cast into distinct groups. Can't be bothered to remember everyone in a show with Loads and Loads of Characters? Neither can some writers.
