Do the RO's have preferred pet names? I bet SC has an abundance of them, my MC would probably use petnames for them as well since "Soul Collector" is more of a title than a name.
In all honesty, it would warm the hearts of all the ROs to be called any affectionate names by MC. 💗
Speaking of names, here are some interesting facts about SC name and how names hold significance in the story:
You were correct in mentioning that SC is more of a title given by those who knew them, as it has been a long time since anyone truly knew their real name or is alive to share it. There's a rumor that hearing their actual name would cause eardrums to burst, leading to fatal bleeding. Others claim that even reading their name aloud would result in choking on one's own blood.
In this world, demons (or creatures, humans, etc.) have status levels based on their energy, abilities, or powers. A being with a lower level cannot utter the true name of someone with a higher level than them. This ability to say names becomes a clear indicator of one's status level.
It's important to note that human energy varies, and their names can be spoken by anyone. For example, Aurelian has angelic blood in him, so he can't be considered purely human. However, being a half-blood, he has the ability to lower his energy level, allowing others to safely address him. But if he desired, he could exert dominance over others through his energy.
