After Saving the Demon Slayer from the Start, Muzan Gained Another Traitor

Blurb:

The Ice Emperor, tiebreak fanatic, stamina king, old-school whale, and one of the three great conglomerate heirs in Japanese manga and anime... Keigo Atobe suddenly gets bound to a System. It has a name perfectly suited to the dazzling aesthetic of the Great Atobe:

The King of RPGs.

[A movie star (crossed out), but destined to be the Great Atobe]

As the saying goes, a director who doesn't want to be the Great Atobe isn't a good actor. The fifth stop is the world of Demon Slayer, a journey to wipe out every last demon.

Who knew the story would break down completely, with hell waiting from the start?

The one who leaves home to sell charcoal is Nezuko, while at home are Tanjiro, wearing those earrings that are guaranteed to trigger Muzan's trauma, and his helpless family.

Atobe hasn't even landed yet when he makes a last-second teleport to save them. Carrying the gravely injured Tanjiro, he dodges Muzan's frenzied killing blow, but is contaminated by demon blood, and the two of them both transform into demons.

And so two of the most unusual demons are born. One overcomes sunlight at an extraordinary speed, never eats people, and is incredibly powerful. The other refuses to be beneath anyone from birth and fights tooth and nail to become the Demon King.

Nezuko, who follows Tanjiro's original path, is rescued by Giyu and sent to train. She grows stronger in no time. “Even as a demon, my big brother is still the handsomest guy for miles around!”

When the final battle in the Infinity Castle arrives, Muzan faces:

The Radiance Pillar Nezuko, wielding a Nichirin Blade, and Tanjiro, the strongest demon, who has mastered Sun Breathing.

And the new Demon King Keigo Atobe, dancing amid a sea of roses and commanding the battlefield while wielding a tennis racket, a weapon that shouldn't be especially deadly, yet somehow is.

Muzan: The fastest Infinity Castle raid in history. Who gets it, guys?

#Is there something off about this generation of Hashira and demons?#

#With so many demons, guess how many are traitors?#
