The resurrected Great Maou Anther attacks all mankind.
In the past, the ancient alchemist civilization was almost completely destroyed before its mighty power, and it seemed impossible for the current human power to resist.
However, the ancient alchemist civilization had left a way to fight against Anther.
── The sealing magic by the "successors" of the three wise men.

Two of the successors had been found, however, the Great Maou's army attacked once again.
In the midst of it, New Mark, who was working under Anther, kidnapped Karen, which broke the hero Yuuki's heart.
Yuuki was forced to act like a hero, which may have been why he became so depressed. However, Shad's pep talk inspired him to get back on his feet and hold his Holy Sword once again for Karen's rescue.
While looking for Karen, the explorers discovered Mark's Homunculus factory.
Destroying the factory would prevent Mark from reviving, but of course, the enemy noticed this plan and counterattacked.
They managed to win the fierce battle and destroy the factory.
At the same time, Yuuki succeeded in rescuing Karen and discovered that she was the last successor.

Just when everyone was ready to attack, bad news came in.
── Anther, who had been sleeping this whole time, had revived.

The final battle is awaiting our heroes.
At that moment, an unexpected person appears and proposes a countermeasure against Dasha, the Queen of the Krishna Kingdom, who's playing an important role on the enemy side...

Will the explorers be able to defeat the Great Maou...?
