Yuuhi Town Ouendan

The Yuuhi Town Ouendan (Evening Sun Town Cheer Squad) is an oendan that serves the citizens of Yuuhi Town in Tokyo Japan. It appears in both installments of the ''Osu! Tatakae! Ouendan duology (Osu! Tatakae! Ouendan and Moero! Nekketsu Rhythm Damashii Osu! Tatakae! Ouendan 2'').

Overview
The Yuuhi Town Ouendan is distinguished by their black traditional gakuran, along with red armbands and headbands. Female members of this team are in the Cheergirls group, in which they serve as more American cheerleaders in blue garb and yellow pom-poms. There are eight known members in all, comprising of five male oendan and three Cheergirls. The Yuuhi Town Ouendan are known for their hot-blooded passion, hence their adoption of red as one of their team colors. The Ouendan always sends three team members to a mission, comprising of one leader and two backup dancers.

Fight song
The Yuhi Town Ouendan are also known to have their own fight song, played at the end of tutorials and reprised after the completion of each game's final mission. The lyrics of the song roughly translate to the following:

''Cheer! Cheer! Cheer!'' Put your fighting spirit together! ''Cheer! Cheer! Cheer!'' We are the cheer squad!

Go!...Fight!...Cheer squad!

History
The Ouendan's earliest known assignment was to assist Tsyoshi Hanada, a promising student, in gathering morale and resolve to pass his exams. Following this episode, they responded to various other distress calls throughout the city for assistance in overcoming problems, including one from the racing horse Biridon in mustering racing skills to catch a thief, another from a ramen shop owner starved for customers and another from a boy trying to fend off a bully in a game of dodgeball. They have even responded to calls from unusual sources, including a violinist suffering from a stomachache and the Egyptian queen Cleopatra back in ancient times.

Eventually, the Ouendan use their ability of inspiring morale through dance to resolve more dire crises, starting with one in which a man killed in a motorcycle accident is trying to make good of his only chance to tell his girlfriend he loved her, followed by incidents where the city falls under attack to a giant mouse or alien robots. After these episodes, humanity is endangered by the approach of a descending comet that threatens to bring mass extinction on impact. The Ouendan rally everyone in the city and eventually the world to put forth their best dancing skills to unleash a beam of kiai (spirit) energy to destroy the comet and save the world.

Six years after the comet was destroyed, Hanada calls the Ouendan for help again to help him apply for and win a job. Around that time, a rival oendan group, the Asahi Town Ouendan, emerges, offering the same help as the Yuuhi Town Ouendan in another part of Tokyo. The two Ouendan occasionally cross paths and exchange confrontational looks, but otherwise make no efforts to interfere or assist with each other's operations. In the meantime, the Yuuhi Town Ouendan continue doing business as usual, assisting clients like a barber trying to outwit his rival, a retired folk hero who has to deal with an ogre threat and even a boy struggling with potty issues. They later on notice the Asahi Town Ouendan taking care of what appears to be the ramen shop owner's cat on a rainy day.

After the Asahi Town Ouendan cheered on Mana Shiratori, the figure skater coping with the sudden death of her older sister, to success, the Yuuhi Town Ouendan respond to an imminent danger to the city, the kaiju-sized Nyaragon, and rally efforts to build a powerful robot to destroy it. Shortly after, another disaster befalls the world: the sun runs out of fuel and ushers in a dangerous ice age that brings down deadly ice crystals and cold temperatures. The Yuuhi Town Ouendan rally people to safety along with their rivals until they suddenly see a huge chunk of ice coming down on the latter. The Yuuhi Town Ouendan push their rival Ouendan out of the way and are crushed by the ice in their stead. All the people helped by the two Ouendan, along with the Asahi Town Ouendan, decide to chant "Ouendan" to help the frozen Ouendan break free once again. The two Ouendan then unite to encourage everyone to charge enough kiai through song and dance to recharge the sun and keep life sustainable once again. Doing so successfully, the two Ouendan mutually respect each other and part ways.
