Demon Lord Dale Watts, having unified the Demon World, begins his invasion to conquer the Human World.

Meanwhile, a decree was issued in the Human World: "He who draws the Angelic Sword shall become the Hero and slay the Demon Lord."

Upon hearing this, Dale Watts transferred his soul and magic power into a human body and infiltrated the ritual, intending to personally destroy the sword and eliminate the Hero. However, no one could draw the sword.

As spectators were also allowed to participate in the ritual, it became Dale Watts' turn. Unable to escape, the moment he reluctantly gripped the sword, his magic power was absorbed, the sword's spirit Erin materialized, and the sword was drawn.

By drawing the sword, he was recognized as the Hero and given the command to slay the Demon Lord… but that Demon Lord is himself.

And so begins a mysterious adventure log about me going to slay myself.
