DVD OVA of Witch Craft Works bundled with the eighth manga volume.

Tiara, a princess from the kingdom of Waleland, travels to the city of Mamkestell to attend a prestigious academy for those who practice magic like herself. After passing a test to prove her eligibility, Tiara reunites with her childhood friend Rosetta, who is also a student there. She then joins and meets Rosetta's group: the athletic Lavie, the reliable Ashley, and the bookish Lynette—all of whom Tiara quickly befriends. In this institution, students are placed into one of three ranks based on their test score: group Noir being the highest, followed by Rouge and Lapis. Tiara's group is ranked Lapis, and if that was not enough, those who fail while ranked Lapis face expulsion. Realizing their dire situation, Tiara urges everyone to start taking their activities more seriously. On top of this, Tiara has one more purpose for excelling at the academy: to become more like her elder sister, who is a very skilled singer. However, to reach the stage that she desires, she will have to overcome many challenges, along with her companions, as she continues her magical journey.

Throughout life, people come and go, eventually departing with a goodbye. For childhood friends Natsumi Aizawa, Yuka Hanaki, and Rinko Tamaki, they are confronted with this harsh reality when they are told their group's fourth member, Saki Mizukoshi, is moving away at the end of summer. With this news threatening their friendship, the four girls seek out a magic stone from local folklore—hoping to use its rumored wish-granting powers to keep them together. After following the steps of the supposed legend, they are surprised to discover that the magic is real. While the summer's end looms over the horizon, Natsumi and the others use the stone to ensure they have no lingering regrets until the end. But regardless of what the future might bring, these four friends will never forget the colorful miracles they experience during what could be their final summer together.
