Club Stub

""This confirmed what I had thought before but had never been able to confirm definitively: Shizune and Misha are the student council. The whole student council.""

- Hisao, Katawa Shoujo

School clubs play a big part in the life of any student, and one of the first things a student will do upon arriving at a new school is to check out which club they want to join. So when the new student who will be our protagonist visits the club that will be the focus of the series to inquire about joining, he'll be hoping for a warm welcome into a well-established and thriving group to discuss and share a common interest with. But our hero(ine) gets more than he (or she) bargained for. While the clubroom is strangely empty, the welcome he gets is a warm one, sure enough. In fact, it's suspiciously warm, and perhaps even forceful.

The reason for this soon becomes clear. The club was just about to be disbanded when our hero appeared. The most common reason the club finds itself on the chopping block is because of low membership, and even if it's not the only reason, lack of interest will still be at least a contributing factor. The remaining membership is thus very eager to recruit new people. It goes without saying that the protagonist will be the prime target. This hapless first-year student will find himself with the club's very existence on his shoulders, and the first challenge our hero will face is to help the club gather the required minimum number of members and re-establish the necessary infrastructure to stop the school's authorities from giving the club the axe.

Starting a series centered around a school club with this plot has a few functional advantages. Since most members will be just as new to the club as our hero, plenty of As You Know exposition gets justified. It is also a good way to explain why new characters line up in a Debut Queue rather than being introduced all at the same time, and why the club ends up as a Ragtag Bunch of Misfits.

Keep in mind that not all clubs with low membership will be in danger of being dissolved. They might exist outside of a school setting and are not beholden to any school authorities. It might even have been started by an antagonist specifically to exclude the hero or another positive, optimistic character. Such a club will stay comically small, however, since so few people find the victim unlikable.

 * Clannad has Nagisa trying to restart the Drama Club by herself until Tomoya joins up. From there everyone Tomoya comes in contact with joins pretty readily.
 * In Eyeshield 21, the football team at the start of the story consists of only two players- they're able to play games only because Hiruma blackmails random students into joining the team when necessary. One of the central parts of the story is Hiruma discovering Sena's exceptional talent as a running back, forcing him to join the team permanently, and then exploiting his reputation in such a way that he can find other worthy permanent players. Even then, it takes a long, long time for them to finally assemble a permanent full team.
 * This is one of the reasons the series is so fond of Who Needs Overtime; since they have just enough guys to field a team, virtually all of their full-timers play on offense, defense, and special teams - meaning that the team would simply be too exhausted to play competently should a game get to overtime.
 * Kenichi: The Mightiest Disciple has the Gardening Club, the only members of which are Kenichi, and a girl from his class.
 * The Astronomy Club in Sora no Manimani was nearly disbanded before Saku joined, but with Hime eventually joining and Edogawa hanging around enough that he may as well be a member, it was saved. Mihoshi pretty much forced Saku into it, though.

 * Bamboo Blade: Kirino Chiba, as the only active and participating member, was Kendo Team Captain by default. Aside from her, the only members were Toyama and Iwasa, who only showed up to bully the newbies and girls, and Saya, who had recently stormed out of the dojo in a huff ... again ... and had yet to return. Everyone else had either graduated, were about to graduate and were too busy studying for final exams, or were driven off by Toyama and Iwasa's bullying.
 * Nichijou has the infamous Go-Soccer club, with just two members that are stuck doing nothing since the club 'president' made up the Word Salad Title for the club. Amazingly, this draws actual Go-Soccer practitioners down the line.
 * The Fashion Club in Heartcatch Precure only had one member when the series started - founder Erika. She nearly manhandles New Transfer Student Tsubomi into joining, but calms down enough so that Tsubomi joins on her own and later convinces others to join by giving them discounts to her mother's clothing store Fairy Drop. By episode 7, Erika nearly loses the club because Student Council President Itsuki left school early and Erika and Tsubomi couldn't give her the list of club members. They're able to chase her down and save the club, though.
 * In GA Geijutsuka Art Design Class, this is what happened to the Art Club. Due to, the club now only has three members. Downplayed in that while the club was eventually saved by merging with Campus Environment Club, the other club only have one member—that other club can't be disbanded because it provided volunteers to clean the school campus, and Sasamoto-sensei Exploited this to use it as a "shell" to acquire other clubs so that she can have a smoking room.
 * The titular club in Genshiken has a few members at the start, but arguably qualifies for this trope by dint of their sheer laziness (as the story makes clear later).

Real Life

 * In a Made for TV Movie about the origin of the Guardian Angels I saw many many years ago they started as a club of two, who were joined by a couple of other people who had a club of two of their own doing basically the same thing. The "other club" which wanted to join with the proto-Guardians called themselves the "Magnificent 13" to make people think there were more people in the group than there were. (Details may be hazy, like I said it's been many many years.)
 * Often school clubs based on once popular activities and fads will fade out as older members graduate and incoming freshmen don't want to join. So even though in the past the club might have had dozens of members it is now just a Club Stub populated by a couple die-hards
