Good luck! There are endings where the MC dies trying to help others, but either someone else has already died or it's so early in the story that it's pretty much inevitable that more people are going to die as the journey goes on, . The MC of this game is pretty important to have around. With her gone there isn't much hope for the others. The guide and just one other person, or possibly only the guide, will make it to the end. Though the MC won't be around to see it. I'm sorry it's such a downer, aha. Being that MC is a rough job.
Well that's quite unfortunate, haha. It will make the experience even more heartbreaking, knowing that I cannot sacrifice myself to save the rest. I'm sure this game will be quite the emotional rollercoaster, can't wait to play it!
