cosette isnt a spirit user thats why the spirits punished them
i think idk just a thought
Ive read a spoiler long ago and cant remember that well so read this with a pinch of salt
The sister already died and was possessed by a demon that manipulated(?) the spirits and since MC was a spirit user the spirit gods were angry and punished the people and hence why the magician turned back time and keeping MCs memory (it was probably her dad that made the contract with the magician and chose Kiera to keep her memory)
Wait what that actually makes sense??!?!
i’m confused bruh how did the sister see the spirits and keira cant? i read a spoiler that after keira got executed the spirit gods or something punished everyone...why would they punish them if the sister is a spirit user too? confusion
