The adventure in the World of Witches continues, with Sasami meeting a boy named Amitav who seems to know about her. The loneliness of Misao fades away when she meets other lonely girls in this world!

After Sasami thinks about Amitav after completing a school assignment, she and Misao travel to the World of the Witches again. However, a friend has to save them when they get lost.

While the team of Sasami is behind, they have one event remaining, struggling to cover, with magic, the bare branches of a tree with blossoms of happiness and love, the father of Sasami gives Ms. Washu news which startles her.

Having impressed the judges at the Magical Girl Tournament, the Magical Girls Club is invited to a special Magical Girls summer camp in the World of the Witches.

Sasami feels weird about some the skills the Magical Girls are learning at the camp, as does Ms. Washu, who sees the potential to either right past wrongs or do the opposite.

The storytellers have a short window of time to protect the Magical Girls from the power of the Great Cauldron, especially when the Chief Sorceress is requesting that Sasami and her friends reach into the deepest, darkest parts of their souls.

When Ms. Washu bans the Magical Girls from going back to the World of the Witches, Misao becomes upset. Little do they know, but the World of Witches will come to them in a way they cannot expect.

The World of Witches' dark magic has changed the attitude and appearance of Misao, resulting in a dangerous rescue attempt by Sasami.

While the Chief Sorcess wants some of Sasami's power, the Magical Girls understand that the magic of friendship itself can effectively battle evil. As such, they realize that they can trust each other and work as one, then humanity can be saved.

Even though normality seems that it is returning, Itoki tells them of a new magic trouble, with Ginji realizing that he can only stop this by hurting those closest to him.
