Hyperdimension Neptunia Mk2

(missable!)

There are many requirements for this ending:

First, you need to view all three Demon Sword rumor events. Raise the shares to at least 55% in Lastation, Lowee, and Leanbox. Use the Chirper menu in each city and talk to the following: Slayer in Lastation, Arfoire Mama in Lowee, and Mid-Level Explorer in Leanbox. This can be done as early as Chapter 2, though Chapter 3 is also a good spot to get them. Here is a video of all the Demon Sword rumor events, credit to MasterLL:

Lastation event starts at 0:00, Lowee event starts at 0:28, Leanbox event starts at 1:08.

Second, once you reach Chapter 5, after getting Neptune, recruit the goddesses in Lastation, Lowee, and Leanbox.

Third, increase Planeptune's global shares to over 55%.

Lily Ranks do not matter for this ending.

Once you finish the second CFW Magic fight, instead of going to Chapter 6, you head to a Chapter called "Apocalypse: The Savior's Sorrow", and you will be locked into this route. Complete the game for this trophy.
