Not so with the Devil!

No, why are you hanging on? No, why would you remain loyal until death? That's not the case with the Devil. I will practice swordsmanship with you, feed you my blood to detoxify, save you from danger, show you all the flowers, increase your favorability, and after completing the main plot, you should forget about me and start over automatically. Why are you crying? Isn't this a game with multiple endings?
