Conquest Ending

"I won’t let that happen. I’m still determined to keep that from happening, and I’ll use any means necessary. Still, what if the people’s decision is inevitable, like she said? What if I’ve chosen the wrong solution? These thoughts... Sometimes I feel they’re suffocating me..."

- Nepgear in the Conquest Ending

The Conquest Ending is an event in Hyperdimension Neptunia mk2 and one of the multiple endings of the game. In this ending, Nepgear wipes out all the Goddesses and ultimately dooms Gamindustri.

 * See the Chirper event with Mid-Level Explorer in Leanbox. Leanbox's local shares must be at least 55% (none for Re;Birth 2) to see this event.

 * See the Chirper event with Slayer in Lastation. Lastation's local shares must be at least 55% (none for Re;Birth 2) to see this event.
 * Must have recruited all of the CPUs (Noire, Vert, and Blanc).

Aftermath
With the outcome favoring Nepgear, Arfoire was finally defeated. As Nepgear was about to slay Arfoire with the cursed sword, Arfoire didn't hesitate to dodge, letting herself be impaled. Arfoire explains that she let herself lose because Gamindustri was already on the verge of destruction. Nepgear retorts that Gamindustri will be peaceful as long as Arfoire is gone from the world. Arfoire explains that Gamindustri will indeed be peaceful under one nation ruled by one CPU, but there will be no conflict, war, and competition, meaning that mankind will not advance and will soon decay. Nepgear ensures that she will never let Gamindustri fall under her leadership. Arfoire responds that the people will soon demand freedom after a while. She ends her words by saying she is eternal and will come back if called upon again.

News spreads about the CPU's "disappearance" around Gamindustri. Ten days after Arfoire's downfall, Nepgear comes to a resolve to bring about order. As Nepgear went around Gamindustri to restore order and addressing its problems, Nepgear contemplates Arfoire's last words echoing in the corners of her mind. Nepgear ensures herself that she won't let Gamindustri fall and will use any means necessary to do so.
