Nana Komatsu is a helpless, naïve 20-year-old who easily falls in love and becomes dependent and clingy to those around her. Even though she nurses ambitious dreams of removing herself from her provincial roots and finding her true calling, she ends up traveling to Tokyo with the humble reason of chasing her current boyfriend Shouji Endo. Nana Osaki, on the other hand, is a proud, enigmatic punk rock vocalist from a similarly rural background, who nurtures the desire to become a professional singer. Putting her career with a fairly popular band (and her passionate romance with one of its former members) firmly behind her, she boards the same train to Tokyo as Nana Komatsu. Through a fateful encounter in their journey toward the metropolis, the young women with the same given name are brought together, sparking a chain of events which eventually result in them sharing an apartment. As their friendship deepens, the two attempt to support each other through thick and thin, their deeply intertwined lives filled with romance, music, challenges, and heartbreaks that will ultimately test their seemingly unbreakable bond.

In the kingdom of Highland, fairies lived freely until humans betrayed them. Once a fairy has been stripped of a wing, whoever possesses it holds the fairy's life in their hands. Taking advantage of this, humans enslaved fairies, but 15-year-old Ann Halford longs to see the day when fairies and humans are treated as equals. The aspiring confectioner dreams of becoming a Silver Sugar Master just like her late mother. In order to achieve this lofty goal, Ann sets out for the capital of Lewiston, home to the annual Royal Candy Fair. However, to be bestowed the elusive title, Ann's confection crafted from silver sugar must be recognized with a royal medal at the event. Ann hires a sharp-tongued warrior fairy, Shall Fen Shall, to be her bodyguard for the perilous journey ahead. After saving him from his cruel fairy trader, she promises to return Shall's wing to him once they reach the capital, much to his confusion. But as the pair travel further along, the time they spend together grows, and they learn more about each other and their true desires.

Kimito Kagurazaka is a commoner with a fetish for men's muscles—or at least that's the lie he must keep telling if he wants to keep himself out of trouble at the elite all-girls school, Seikain Academy. Kidnapped by the school under the assumption that he prefers men, Kimito is made to be their "commoner sample," exposing the girls to both commoner and man so that the transition to the world after school is not jarring. Threatened with castration should his sexual preferences not match the school's assumptions, Kimito keeps up the facade to protect his manhood. But there are eccentric individuals around every corner who begin to make Kimito's life even more difficult. Among them are Aika Tenkuubashi, a social outcast who blurts out whatever comes to mind; Hakua Shiodome, a young genius; Karen Jinryou, the daughter of samurai who is obsessed with defeating Kimito; and Reiko Arisugawa, the perfect student who has delusions of marrying Kimito. Along with the commoner himself, these four girls make up the Commoner Club, which attempts to teach the girls more about life outside the school, while Kimito gradually learns about the odd girls surrounding him.
