补充说明，你想要包括恶魔在内的其他敌对NPC成为朋友也不是没有办法，捕捉之后再山巅里分配到“拥抱休息室”，等好感度提升到超过10之后，就可以升级为仆人并成为同伴。但要注意捆好了，别被她给跑了:)
Just to add: if you want to befriend hostile NPCs including demons, there is a way—capture them first, assign them to the 'Hug Lounge' at Summit Peak, and when their favor hits 10+, they upgrade to servants and become allies. Pro tip: tie them up tight though... wouldn't want them slipping away. :)
有什么不可能的？我最开始的回复便是“但是......据我目前的游戏进度而言，我没有遇到过哪怕一个派系为“恶魔”的NPC。我所遇到的恶魔类型的NPC均为无派系或者是无法变更好感度（必定敌对）的派系。”
Impossible? But let's be clear—my first reply stated: '...based on my playthrough, I haven't met a single NPC with a Demons faction tag. Every demonic NPC I encountered was either factionless or belonged to factions with unchangeable favor—meaning permanently hostile.'
I don't think there's anything special about it, but I think there's an advantage to joining because you won't receive solicitations from other factions.
加入某个阵营之后接到的任务，其唯一作用就是给你退出该派系。毕竟一个存档只能加入一个派系，仅仅只是方便你后悔了想改投其他派系的时候提供一点便利而已。
The faction quests you get after joining are only for quitting that faction. Since you can join just one faction per save file, they basically just let you regret and switch—convenience feature, really.
