Re:Zero Kara Hajimeru Isekai Seikatsu started as a web novel written by Tappei Nagatsuki, which has since been adapted into a manga, light novel and anime.
The story follows Subaru Natsuki, high school student, who was suddenly summoned to another world on the way back from the convenience store. With the biggest crisis of his life being summoned to another world, and with no sign of the one who summoned him, things become even worse when he is attacked. But when he is saved by a mysterious, silver-haired girl with a fairy cat, Subaru cooperates with her to return the favor.
When they finally manage to get a clue, Subaru and the girl are attacked and killed by someone. Subaru then awakens in the place he was summoned and notices he gained the ability "Returns by Death" and has become a helpless boy that only has the ability to rewind time by dying. Beyond the despair, can he save the girl from the fate of death?
Re:Zero is a fairly strong verse. The witch of envy Satella destroyed half the world, a Multi-Continental feat, 400 years ago and Reinhard with Reid is stated to be a match for her. Most characters range from Wall to Town level with Supersonic+ to Hypersonic+ speeds, with the average character being City Block level and Supersonic+. Echinda, Lewes, and Sphinx with Jiwald are able to attack at the speed of light, Reid and those who are comparable to him have FTL reaction speed, as Reid was able to react to 10 Jiwalds being fired at him at once.
- Rem's Al Huma (City Block level)
- Reinhard's casual sword strike (City Block level)
- Emilia 6 Layers of Ice Walls (Multi-City Block level)
- White Whale's Durability (Town level)
- Puck creates giant icicles (Small City level)
- Puck and Roswaal nuke each other (Small City level)
- Roswaal's Altemillion (Island level)
