On the vast farmlands of Centvelt in the continent of Avrion, the Farmagias diligently tend to their fields. Meanwhile, Ten spends his days slacking off, focused on raising the ultimate monster. One day, shocking news arrives: The Magus Diluculum has suddenly died.

Together with Anzar, who has regained his sense of self, Ten and the others challenge the Magus Diluculum to a final battle. However, even their strongest attacks have no effect on Diluculum. As the world gradually collapses due to the "Grand Harvest Festival," Ten and his comrades continue to struggle desperately, refusing to give up.
