That Time an American was Reincarnated into Another World - Chapter 128: Heartstopper

Alex, An average guy transmigrates to an ancient world. He awakens an ability to farm in an interdimensional pocket space.Far from what he imagined, the planet he was on was completely different from the earth he knew. There were mythical beings, magical abilities and powerful civilizations. All that contradicts his common sense.Let's watch how he survives the harsh unknown world with his wits and extraordinary ability.

To correct the mistakes of his past, a young man is forced to narrow the space between science and witchcraft, as he ventures on a quest to save his world from complete destruction.

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?
