Hope to read the introduction
The protagonist Chise is Chise from The Magician's Bride. I haven't read the manga, so I will combine it with other anime, probably Mary Sue. If there is an OOC note,
Point of difference: The world Chise is set in is a parallel world of Demon Marriage. Because of the time-travel girl, Chise and Elias (the anime's official supporting role) are not together, and their relationship is not close. In the end, Elias did experiments on him because he wanted to save the time-travel girl, and was thrown out as a shield.
All arrangements are needed by the plot, all arrangements are needed by the plot, all arrangements are needed by the plot, important things must be said three times! I still like Elias's long legs and bones, but do I like them or abuse them? They have no conflict (self-convincing)
In fact, time-travel girls are not bad. In my opinion, not every time-travel girl has to look evil. It's not her fault that Elias saved her, but Elias has this kind of character (whisper bb). In the original animation, Elias wanted to sacrifice the life of an innocent girl to save Chise, but Chise stopped him. In the parallel world, Chise is no longer the most important person to Elias, and his natural status is almost the same as that of the innocent girl.
Well... These are probably the red flags I think. If you really hate splitting CPs, be careful! If there are other bad points, then I have no choice. I really can't stand the spread in the upper right corner. I'm not good at arguing, and I don't want to accept personal attacks. .
