[DISCONTINUED] Regrets and Wishes: To the Parallel Past

(DISCONTINUED. Please read the entirely-rewritten version instead: "Regrets and Wishes: One More Chance".)

It's been years after the Great Tenma War subsided. A certain demon lord sits in front of a pile of papers. After talking with his Partner, they finally get an idea. Pushed by his desire to save his friends, as well as to get rid of those papers, he goes to the parallel past of the world, accompanied by his Partner, restarting everything from the very start.

However, as they go through their new journey, a mysterious feeling begins to bloom. They're not yet to understand it. But surely, it will guide them, leading to various major events that didn't happen in their original past.
