- Description from Novelupdates

Setsuna Shū is a magical girl with temporal magic that allows her to go back to the past whenever she performs a certain action. She works as a magical girl, hunting monsters and helping people… or at least, that’s what she lets everyone believe. In truth, she made a contract with a demon so she could return to the past and rewrite the future.Her real reason for turning back time is to save her “sister.” As a child, she had no parents, relatives, or friends. When she was finally adopted, her sister became her entire world — and for her sake, Setsuna wouldn’t hesitate to sacrifice the world itself. She gave up her original gender, her past “existence,” and even parts of her freedom in a demonic contract, all for the sake of saving her sister and taking revenge on the monsters that hurt her.But… is that really all there is to it? Or is Setsuna, in the end, partially responsible for everything that happened?

A millennium had passed, and everything had lost its meaning in his eyes. Many heroes emerged from generation to generation, but he stood the test of time. That was his life, waiting for someone to come along and defeat him, but no one did. Nobody dared. Nobody tried.How can he allow this to happen? With the aid of his magic, he rose from his throne and set out into another world in search of excitement and, perhaps, a worthwhile adventure.What would happen if this last boss decided to venture into the human world for fun?
