Mash beats Silva, defeats the giant forest scorpion, and successfully completes the joint extracurricular activity. The five silver coins collected become one gold coin, and Mash learns about the existence of Lang Dorm’s core students who hunt coins — the seven students of the Magia Lupus. But later, Mash, searching for his next classroom, wanders into the Magia Lupus stronghold. Although he makes it out alive, a black shadow approaches Mash and his friends while cleaning out the owl huts….

After Mash and Lance defeat Olore and Anser of the Magia Lupus, Abyss appears before them to collect his comrades, leaving behind a disturbing atmosphere. Mash discusses the future with Lance while baking cream puffs when Lemon rushes in. It seems that Tom has temporarily lost his ability to use magic. That night, while Mash and his friends explore the school to unravel the mystery, they discover a strange-looking Lemon....

After chasing Lemon and discovering a door to the basement, Mash and the others are confronted by the Magia Lupus at the bottom of their way down. It's Lance vs. the Third Fang Wirth and Mash vs. the Second Fang Abyss. The decisive battle begins!!

While Mash and Lance beat their respective opponents and proceed to help Lemon, Dot and Finn battle the Fifth Fang Love and the Forth Fang Milo. Dot fiercely struggles against Love's strength, but due to something unexpected, his magical power suddenly increases, and he undergoes a transformation. The secret is...?

Even with a win over Love, Dot is battered and bruised. Milo gives up on using petrification magic on Mash and launches an attack on Dot. Suddenly, the Divine Visionary Rayne appears, and Milo collapses in an instant. Rayne was informed by Wahlberg that Innocent Zero's agents were coming to school, and he showed up to respond. Meanwhile, Mash has made his way to the First Fang Abel. Mash reveals his quiet rage. What will be the course of this decisive battle?!

Mash overcomes Abel. Other than Lemon, Mash and the others are overjoyed after the other students are released from being transformed into puppets. Meanwhile, Rayne confronts a member of Innocent Zero who disguised himself as Lance. But he is left behind, and the Innocent Zero agent escapes to go after Abel, who is no longer of use. A new threat creeps up upon Mash and his friends...!
