Rei is the Dragonborn despite her young age. The Divines fear something worse than the end times if she were to die. A battle for soul would tear the world and their powers apart. So they send her 15,000 years into the future. There she mets a cape baldy and blond cyborg and joins them on their journeys.

You think your Dragonborn is so overpowered that the quests of Skyrim become boring? You think no one in Skyrim properly acknowledge your mighty deeds that save the world? Then I guess you can understand a bit about how Saitama feels as the Dragonborn... or not. As an inevitable result, this Elder Scrolls story with One Punch Man characters is AU... Very AU.

Saitama was just a seemingly average man. He had a one bedroom apartment, went grocery shopping, and did his job as a B-Class Super Hero. Well seemingly average was said. On one night, Saitama stumbled a strange wall, now he is in a world full of magic, intrigue, monsters, and Market Stalls. The very foundations will of Tamriel will be shaken. Oh and Saitama turned into a Bosmer.
