I don't suppose you mean Puella Magi Madoka Magica?
Also, I rewatched the first episode for all the foreshadowing and whatnot, and came upon the following mind screw:
So the alpha world line, in which SERN takes over and Mayuri dies, is made possible by the first D-mail, in which Okabe writes to Daru that Kurisu got stabbed at the lecture, effectively preventing it from taking place.
The beta world line, in which Kurisu dies and WW III takes place, is made possible by Okarin seeing Kurisu apparently or actually murdered, and her father getting away with the time machine research.
How does Kurisu living change either world line to the Steins Gate world line, if in either case, Okarin will still always send a text to Daru about the apparent or actual murder, and unknowingly and unintentionally sending the first D-mail?
Or am I just thinking about this wrong?
