Hyperdimension Neptunia The Animation: Little Purple Sunshine

The third and final installment of the Neptune OVA trilogy introduces a dangerous new threat. The villainous Magiquone arrives with a secret scheme against the goddesses, bringing along a mysterious entity known as Level Trick to challenge them in battle. When the goddesses lower their guard, Level Trick unleashes a devastating "Level-Down" attack that strikes all four of them. However, the blast's aftermath unexpectedly engulfs Magiquone as well, scattering everyone involved. Alarmed by their sisters' sudden disappearance, Nepgear and her companions launch a desperate search. They eventually locate Noir and the other goddesses, only to discover that the Level-Down attack has transformed them into young children. To make matters worse, Neptune remains completely missing. Unbeknownst to them, Neptune and Magiquone are now living together on a vast eggplant farm. Both have been reduced to their younger forms and have entirely lost their memories due to the attack's lingering effects. Stripped of their pasts and powers, these eternal enemies must now navigate a strange, peaceful shared life, leaving their ultimate fate an open question.
