In the city of Maebashi, Yuina Akagi is a free-spirited high school girl with a hobby of buying trendy clothes online and taking photos of her life's highlights. One day, a talking frog suddenly speaks to her, sees in her the potential to become a witch, and transports her to the Witch-Verse. There, the frog introduces Yuina to four other girls he has recruited—the cheerful Choco Mitsumata; the composed Kyouka Kitahara; the easygoing Mai Kamiizumi; and the short-fused Azu Niisato who is apprehensive of Yuina's arrival.

Despite the initial clash of personalities, the five girls aim to become true witches. To achieve that goal, they must grant people's wishes in the real world through music—the most efficient conduit for channeling magic. As Yuina learns to control her newfound powers, her journey into a magical life helping others will be far more vibrant than any photo her camera can ever hope to capture.
