Stella Glow: How to Get the True Ending

Stella Glow has a true ending, which isn’t particularly difficult to get. Here’s how to make sure you see how the story really ends:

• Talk to Klaus in the Knight Barracks in Free Time whenever you can. You won’t be able to max out his Affinity, but if you’re unable to talk to him by Chapter 7, that means it’s as high as it can get. If Giselle joins your party in Chapter 10, that means you’re on the right track.
• In the final boss battle, a cutscene will end with Alto having to make a choice. Choose to decline (the bottom option).

That’s all there is to it. If you want to see both endings, use a second save file and accept when given the choice in the final battle.
