Under Haru's tutelage, Zeha's skills grow by leaps and bounds. But when his sword breaks from the strain of fighting the Beom, he's forced to look for a new weapon in the last place he expected--a history museum. He picks up a rusty relic blade at Haru's insistence, and his mind becomes flooded with visions of an ancient warrior! It seems that there is far more to the Beom invasion than meets the eye, and fate seems determined to bring together the seven warriors to stand against the coming storm!

With fewer witches cropping up in Mitakihara and the surrounding area, many magical girls are embracing their chance to enjoy a break from the hunt— but not Mami Tomoe! Mami wants to know why witch numbers are declining in every city save one. In Kamihama City, the witch population is greater and stronger than ever, not to mention there’s a mysterious magical presence unlike anything Mami has encountered before...!
