There are 3 endings you can obtain in Hyperdimension Neptunia. The only endings that have trophies associated with them are Normal and True Endings. The requirements for each ending a summary will be listed below. Note 1: In order to restore Neptune's memory you must go to each landmass first and speak with each of the CPUs and have them refuse to join you. After that, an event in Planeptune will become available which will lead to Neptune's memory restoration. This must all be done before heading to the final dungeon in Celestia.
