As she heads off to her entrance ceremony at Sainotama Girls' High School, Akane Kikuchi muses over her grade school dream of becoming a manga artist and the lack of progress that she has made. When she finally arrives at school, she is surprised to learn that she is once again in the same class as her two best friends: the deadpan and emotionless Shiori Saginomiya and the hyperactive and ridiculous Nozomu Tanaka. Tanaka then comes to the obvious realization that she can't achieve her grade school dream of being popular with the boys and getting a boyfriend by going to an all-girls high school. In desperation, she begins asking the girls in her class to introduce her to their guy friends. Her classmates, however, are anything but ordinary. From a grandmother-loving loli to a reclusive chuunibyou to an overly analytical stalker, each one is given a fitting nickname by Tanaka to accentuate their weirdness. And so begin the wasteful days of these high school girls, each day kicked off with a simple question: Hey, wanna hear something amazing?

Joshiraku follows the conversations of five rakugo storyteller girls relating the odd things that happen to them each day. Their comedic and satirical chatting covers all kinds of topics, from pointless observations of everyday life, to politics, manga, and more. Each girl has something new to add to the discussion, and the discourse never ends in the same place it began. Each of the rakugo girls has their own unique personality, with the energetic but immature Marii Buratei; the seemingly cute Kigurumi Haroukitei; the inherently lucky and carefree Tetora Bouhatei; the calm and violent Gankyou Kuurubiyuutei; and the pessimistic and unstable Kukuru Anrakutei. These girls—and their mysterious friend in a wrestling mask—give their observations to the audience, either backstage at the rakugo theater or in various famous locations around Tokyo.

Jiyu Nanohana is an ordinary schoolgirl until she runs across a scatterbrained 300 year old samurai who tells her that she is the reincarnation of Yagyu Jubei. With the help of the Lovely Eyepatch she transforms into the legendary swordsman whenever she needs to use his awesome fighting ability, which she needs to do quite often as a rival clan is dead set on conquering Yagyu to satisfy an old family grudge.

Three hundred years ago, in the frigid land of Siberia, Jubei Yagyu engaged in a fierce battle with Kitaretsusai of the Northern Yagyu clan. The duel was costly, as his daughter Freesia was frozen in suspended animation. As a result of global warming in the present day, Freesia breaks free from her icy grave and moves to Japan as a middle school transfer student, where she befriends Jiyuu Nanohana. Little does Jiyuu know that Freesia is targeting her to acquire the coveted Lovely Eye Patch, which Freesia believes is rightfully hers. (Source: ANN)
