Two Girls. One Dream. And the entire world for a stage. At 13 years old, Maya Kitajima seems destined to spend the rest of her life toiling in a crowded restaurant alongside her bitter and unstable mother. But when her incredible acting talent is discovered by the legendary diva Chigusa Tsukikage, Maya finds a new future filled with both golden opportunities and terrifying risks. For Ayumi Himekawa, success has always been assured, yet she longs to be recognized for her own talents and skills, not her famous parents' connections. For both, the ultimate prize is the role of The Crimson Goddess in the play of the same name, a part created by Chigusa. To achieve this goal, both Maya and Ayumi must seek out and conquer every acting challenge, pushing the limits of their talent and endurance to the utmost, until they are worthy of the part… But for one to win, the other must fail!

Mushi-uta's story takes place in the near future. Ten years before the story's opening, strange insect-like creatures known as "Mushi" began appearing. The Mushi are able to consume peoples' dreams and thoughts in return for supernatural powers. At the end of episode one, protagonist Daisuke "Kakkou" Kusuriya encounters a young girl named Shiika Anmoto. The two, in time, become quite close. However, unbeknownst to Kakkou, Shiika is an escapee from a secret prison known as GARDEN where those posessed by the Mushi, known as the Mushitsuki are held. GARDEN's military force, the Special Environmental Conservation Executive Office, dispatches its finest killer to track down Shiika. However, they are faced with resistance from the Mushibane resistance organisation, led by the secretive "Ladybird."

Kouta has girl troubles of the supernatural sort. For some reason, he keeps attracting the attention (and affections) of animal spirits! Having spent most of his life in the country, Kouta is understandably nervous when he moves in with his grandma to attend a high school in the big city. He hoped to make a good impression, but having Chizuru, a beautiful fox spirit, hanging off his arm didn't seem to be the sort of image he wanted to have. She's not alone in her love for Kouta, either. Nozomu, a wolf spirit, as well as other youkai have their sights set on the hapless country boy.

A young boy silently sketches out the forms of the horrors that dwell in his mind. During this adventure into the occult and mysterious, he tells tales that involve dreams of a person with a muscular arm that you must not look at, a hospital with a room that holds a grim secret, and a visit to an eerily silent taxidermy museum. These tales and more are compiled in Yami Shibai 3. Presented in an art style similar to kamishibai storytelling, this horror series stays true to the gruesome and creepy trend that is prominent in Yami Shibai and Yami Shibai 2nd Season.
