Plot Elements

 * Volume 1 details the plight of several characters in hopeless situations who cry out for help. In response, the Ouendan, an all-male cheer squad or an all-female Cheerleader group appear to help each character work through their problems by cheering them through music.
 * The origin of the Ouendan is unexplained, though they are always nearby when help is needed.
 * The Ouendan appear wearing highly stylized black uniforms (based on gaku-ran Japanese school uniforms) with red armbands (for the Cheergirls, blue cheerleader outfits with long sleeves), a common sight at Japanese school sporting events.
 * Most of the scenarios are inspired by modern Japanese culture or are heavily influenced by the Japanese form of print comics, or manga. For instance, the first stage features a high school student distracted from studying for his college entrance exams by his family, while a later stage focuses on a pottery master who has lost the inspiration to create unique works.
 * Most of the stories are presented in a light-hearted or comical fashion, emphasized by absurd storyline twists and the sounds of whistles and cheer shouts as the player progresses through each stage. The one notable exception to this is a love story set to the Hitomi Yaida song "Over the Distance," which is told in a more heartfelt, subdued tone further marked by the gameplay's whistle sound effect being replaced with subtle chimes and the initial loud countdown not being used.
 * While the individual stories otherwise have no connecting theme to them, characters from some stories reappear in others as background figures or supporting characters. However, all of the characters reappear in the final story, in which the Ouendan must lead the entire world in a cheer to save Earth from being destroyed by an asteroid.

Moero! Nekketsu Rhythm Damashii

 * Moero! Nekketsu Rhythm Damashii follows more or less the storyline from the original volume, and is set roughly six years after.
 * Whenever someone is stressed out or backed into a corner, all they need to do is shout "Ouendan!" (Japanese for "Cheer Squad"). Then, the Ouendan appear (usually out of a place like a closet or waiting there while eating ramen) and use cheering and dance to help that someone through their troubles.
 * The original Ouendan from the Yuuhi Town (signified by wearing their long Gakuran jackets and for the Cheergirls, signified by wearing their blue cheer outfits) are still present, cheering people on. However, a new rival Ouendan from the Asahi Town appear that challenge the original Ouendan in skill and cheering (the "new" Ouendan are signified by their blue military-style outfits and for the Cheer Maidens, signified by wearing their modest red cheer outfits).
 * The individual stories are all unrelated, but characters featured in one stage may appear as background or supporting characters in another.
 * One can also see characters from the first volume game as lead, supporting or background characters, such as the pottery maker from the first game that appears as a guest at a hot spring, and gifts the hot springs family with new pottery work should the cheer squad be successful.
 * In the final act all of the characters unite when the two Ouendan join together and once again lead the entire world in a cheer to save Earth when the sun's activity stops, plunging Earth into another ice age.
