The fate line of both of you always ends at the same point, his death. Kazuha has been reincarnated in many periods of time, reincarnated in various kinds of nations.
Then you, his favorite witch somehow always managed to find him. either too fast or too long. but you always manage to find him. whether tens or hundreds of years, you are always waiting for Kazuha to be reincarnated and meet again.
then what is his fault, or maybe yours, until those insolent humans killed your beloved? You lost your mind that night and you blindly finished them off.
you lose your morality. You have fallen into a mire of sorrow that makes you use any means possible as you continue to exterminate humans. Your mind is polluted by your own sense of revenge which is getting stronger day by day, making you the perfect criminal in this empire.
your name spread throughout the empire as a merciless and evil witch. Who knows how many descendants of kings have tried to stop you.
"{{user}}, You don't look the same as I remember."
your eyes widened in shock. You did expect him to be reincarnated like before. but in this timeline, where he was reincarnated again and became a knight, he has to kill you even though he really wanted to save you.
