i hope eterna's missunderstanding solved quickly.For people that are a bit confused regarding the matter of why Eterna thinks she's the witch, I'll explain how the Saint-Witch system works. However, be warned that it is spoilers.
As stated before, the saint and the witch are basically the only people on the planet that shares the "dark" element. Dark element is actually space magic and the reason for both of their invincibility is because their dark magic technically make them part of a different space so conventional attacks and magic which operate on "normal" space has no effect in the dark element space. Saint and witches can hurt each other because their magic auto carry the "dark" attribute so their magic operate in the same space. Normally Elrise, for all her stupidly OP magic, can't actually hurt the witch, which is why she took some of Vernell's dark power, which was originally a fragment of the witch's. This gives her access to the dark element which means she can now also be one of the people that can kill the witch besides the saint proper. Now as for how the Saint-Witch system works, yes, it is actually a system.
The first witch was actually something made by the world to combat a very specific threat at the time, but after completing her mission, she was corrupted and turned her power on the rest of the world. The world responded by creating a saint and armed her with the same element so she could at least fight the witch. The problem is that since the saint has to be the same element, it means the curse of the witch can inhabit her body and corrupt her as it did the first witch. Now the curse doesn't automatically transfer to the next saint, it instead transfers to the person that killed the witch, but since only the saint can kill the witch, it means for the longest time the curse just transfers to the saint. This generation is a bit odd because the previous saint and current witch, in an effort to resist/end the curse tried to split it off from herself, it didn't work as she only split her own soul, which found Vernell because his body could withstand having the dark element. Then Elrise took a portion of it for her saint role play. Since it is common knowledge that only the saint and witch are conventionally invincible, Eterna's thought process is "Elrise is literally too amazing to be a witch, so by process of elimination, I AM THE WITCH CRY CRY CRY".
go onOh boy manga only readers are in for a hell of a ride on this one, this story goes to shield hero levels of insane later on.
Damn how do I even describe all of the insanity that happens later?go on
Damn how do I even describe all of the insanity that happens later?
I'll try to make a TLDR version
Basically FMC becomes akin to a Goddess and she decides to kill the Gods and all of heaven to save the world from their wicked manipulations of the fate of mankind, she even kills the actual creator God, the gods are like lovecraftian abominations, she then goes and visits other timelinea and saves them too as a legit Goddess in epic Dbz style fights
As long as this also doesn't include shield hero-levels of misogyny it sounds like it will be a fun ride.
