To get the Revival endings, a few things must be done.

1. In Zero Dimension, you must see the conversations about Uzume's memories of Histoire. If you watch every Zero Dimension conversation, you won't miss it.
2. In Hyper Dimension, for every Goddess's arc besides Neptune, you must get their shares to ~40% to cause a conversation to appear where the Goddess will be sleepy, and might see a dream. The easiest way to do this is increase Public Relations up to the point where the event will trigger. (Every time Public Relations increases a level, the nation's shares will increase, so you can do some combination of quests and investing to trigger the event).

• 1. Noire has 1 required quest in her arc that brings up her shares, so you do not need to grind for money for Noire. Even if you rush the arc, you should have enough money before entering the golden summit to get Public Relations to level 3 and trigger the event.
  
• 2. Blanc has no required quest, so sadly she needs to grind for money in her arc. Fight a few extra mobs or run a quest to get Lowee's Public Relation to level 4 to trigger the event. Remember, you can sell back the processor parts you get from Public relations for a reasonable 2500 credits, and if you don't need healing items, you can sell those as well, making the money grind almost unnecessary.
  
• 3. Vert is like Noire except with 2 required quest in her arc, so just follow the same advice as 1.

3. Neptune's arc has a total of 4 events you must see to trigger the Revival end, many of which are easily missable, so please read through every step before doing this. Luckily, Neptune, inherits all the money from the previous arc, and if this is your 2nd playthrough, she also inherits all the money from your previous run.

• 1. As soon as you can access Sakura Tree Row, a quest will appear to kill 10 Dogoos. Before beating the boss in Sakura Tree Row, complete this quest, and check Conversations, to see a memory of Histoire's.
  
• 2. After defeating the boss in Sakura Tree Row, a quest will appear to kill 10 Delinquent Cats. Complete this to trigger Chuko's first event.
  
• 3. After 2, you'll unlock a quest to kill 8 Red Dogoos. Complete the quest to trigger Chuko's second event.
  
• 4. Finally, raise Planeptune's shares to ~60% to unlock a conversation where Histoire will become sleepy, and have a dream

4. Finish the Hyper Dimension however you want, and just follow the guide for the Ascension route from here. If you did everything correctly, during the final scenes that lead to the Ascension Ending, you'll see Neptune break the 4th wall saying that their actions need to change if they want to reach a happy end.

To trigger the Ascension Ending, first defeat the boss in Channel Space, the first dungeon in Heart Dimension. Upon leaving the dungeon, 4 green exclamation points will appear on the map. Before entering the next dungeon, create routes and go to each of these exclamation points to see each Goddess's dream. Afterward, you're free to progress in the story however you want, and you'll get the Ascension Ending (assuming you didn't do the extra things required for the Revival Ending).

Triggered same as Ascension Ending, but do not watch at Goddess's dream.
