Little Purple Sunshine - S0.E6

Arfoire has a new trick up her sleeve to defeat the Goddesses - a secret monster called Level Trick. During a fierce battle between the Goddesses and this new enemy, Level Trick hits the Goddesses with the "Level Down" attack - a skill that reduces your level and age. Suddenly, the Goddesses age rapidly declined, as well as Arfoire who was accidentally struck by the Level Down attack.

Nepgear and her sisters attempted to find the Goddesses after failed attempts to contact them. They eventually were able to find all of the Goddesses, except for Neptune...

Meanwhile, Neptune and Arfoire were now living together at an eggplant farm. Because of the Level Down attack, Neptune and Arfoire now have amnesia. As former mortal enemies, what will happen to the unlikely duo living together?
