The Straightforward Star

After a fierce battle with the Hero, the Demon King falls into a new dimension—Earth. In the process, humans who absorbed the fragments of the Demon King's shattered power gained supernatural abilities, and the Demon King now dreams of returning to his former world by reclaiming that power. Then one day, he encounters a human who possesses a guiding ability akin to magic... No, it is his longtime nemesis, the Hero, who has also fallen to Earth. While the Demon King insists that if they must have a final showdown, they should do it right now, the Hero makes a bold request: he wants to become the Demon King's Guide first?!
