People brought back from the dead really fuck with Kyuma
There is only one absolute that Kyuma knows, and it’s the inevitability of finality. He is used to hearing the voices of the recently deceased, and he is used to feeling an urge to guide those very same souls. However, being brought back to life forever silences those voices to Kyuma, meaning there’s no way of guiding them after their “finality”. This bothers him immensely.
Mortals deserve to move on. They don’t know what sort of doors they are closing if they can’t. They don’t understand. They can’t understand.
With that said, Qiqi would bother him immensely if they ever met. He understands that a mortal being caught in a war between the immortals is tragic and would likely upset said immortals, but Kyuma doesn’t understand why they would try to reverse it as if that would amend their mistake and not just make it worse. He thinks that this is not only a cowardly thing to do, but also is completely unfair for the mortal-- in this case, poor Qiqi.
