Honestly, I think that the author keep leaving hints about who or what is the mc is but they didn't give us a solid answer bec sometime it's more fun to not know everything.
Since we don't know what exactly is the mc (a human, a soul, a demon etc) it's make the story more interested. The author probably want us to keep guessing and make our own headcanons.
For me, I feel like not knowing what she is make her less op unlike how it show in the manga that she can just slaughter anyone since I don't know the exact source of her power, if it truly her power or it was something else that lend their power to her.
Ohh ok thanks!! Good to know what MC is wasn't really named yet so I don't feel dumb about being clueless lol
Ok I hate to ask this, but I'm a bit lost... What exactly is mc?? Is she a demon, a reincarnated person from modern times?? Or like does she have a split personality disorder?? I'm so fucking confused, it could be due to the translation errors here and there but I'm also a bit slow so that could be the main problem but like can someone explain to me what the fuck is mc
