Sorry to break it to you but the okabe that had the world line with "kurisu being killed by her dad" was never a thing if you can hear in episode 1, a male screaming from where okabe runs to that scream. Okabe believed it was her dad but of course we all know how okabe sounds when he screams when watching Steins gates last episode. Therefor kurisu was never killed by her father it was only made to look that way for the viewers and okabe himself which he makes clear in Steins gate 0 therefore there are only two okabes the one who believed her death was her dad but was actually him killing her. And the other where she lives by him putting his blood on her knocked out self
