Tear Jerker / Hyperdimension Neptunia mk2

• It took three years for IF and Compa to gather the tiny amount of Sharicite - peoples' belief in the CPUs, given form - used to free Nepgear at the start of the game
• The Conquest's ending. Nepgear is forced to kill the CPUs and their sisters, including her own sister. Because they knew that they cannot defeat Arfoire without the Gehaburn. The Candidates express their desire to join their fallen sisters in death. Vert opts to take the sword and with it, Neptune's and Nepgear's lives so that she can live for Chika, and she is murdered anyway by Underling, forcing Vert to ask Nepgear to use the sword to finish the job so that she can at least help stop Arfoire. The kicker? The victory was Pyrrhic, serving not to save Gameindustri from destruction, but making its demise inevitable.
  • Neptune's death is especially hard to watch. While the other CPU's fight back, or only reluctantly resign to their fate, Neptune instead chooses herself to be the last sacrifice to power the blade. What really makes painful is how calmly she presents the idea. It can make one wonder whether she had any desire to continue even if she had the choice, given what it took to get there...
  • Rom and Ram before Nepgear is forced to kill them. Grab some tissues beforehand.
• One of the Chirper endings becomes this in hindsight. When you talk to Blanc in Lowee after saving her, she decides Nepgear's changed for the better, and she'd like to be her friend. If you happen to be on the road to the Conquest Ending by this time, Nepgear will wind up killing Blanc later, the woman who just stated her desire to talk with Nepgear more and have a long friendship with her. Enjoy that.
  Blanc: Fine. I'll try to talk to you more. We'll have a long-term friendship.
• The indication that the sword is what drove Nepgear to kill the others in the Conquest Ending. Every one of the CPUs lives taken is because the sword did something to everybody.
