I'm looking for good examples of time travel stories. By this, I do not mean stories that revolve around time travel, for instance, back to the future, or doctor who, in which someone has a power or device allowing them to transcend time itself and go as they freely will. For the anime fans, I'm looking more so with a character that fits towards Homura Akemi from Puella magi madoka magica. For those who don't know, and don't mind spoilers, Homura was granted powers as a magical girl by the space creature kyubi. She uses these powers as a magical girl to rewind time, trying to keep from a bad event from happening. The story does not follow her though. The story, as the namesake, followes Madoka, who is the protagonist. she does not have time altering powers or anything, and this is where we really get to the bulk of what I'm looking for. Homura, trying to change fate, uses her time travel, and her knowledge created from multiple traversed timelines, to try and keep the bad fate from befalling Madoka. To madoka, who the show focuses on, Homura is a mysterious character, always knowing things and showing up in places she shouldn't be able to know of. The only other example I can think of is Undertale, in the character sans, who is is not confirmed, though he often shows he has abilities that can be explained by time travel. he's able to know things before they happen. He disappears from one side of the room and reappears in the other, he has a range of awareness. So, to sum up everything what I'm looking for is this. a time travel story that focuses not on the time traveler, but on someone else. the story itself does not have to be about time travel, but will include a character who has or may have time altering powers. the story does not focus on the time traveler though, it focuses on someone else, who is affected by the time traveler and who is constantly in focus to notice the time traveler and how they strangely know things and how they are able to move in ways that shouldn't be possible.
