Demon Slayer: The Demon Blade Swordsman and the Graceful Purple Butterfly

[Single female lead]+ [Shinobu Kocho]+ [Original Breathing Style]+ [Raising Muzan as a new father]+ [Redemption for unresolved regrets]

Since ancient times, bewitching blades have often been seen as ill omens.

Slaughter and devouring go hand in hand.

Power is granted, and flesh and blood are offered in return.

A young man named Miyazawa Ryo gives in to the temptation of a cursed blade and sets out to avenge his deceased family.

No one can live forever.

By the same token, no demon can escape the blade!

Until one day, a purple butterfly dances down onto the swordsman’s shoulder along his lonely road. When he looks back, flowers are blooming everywhere he has passed.

Isn’t the road supposed to be nothing but mud?

Purple Butterfly: Swordsman, you seem a little tired. Would you like to rest here with me?

Swordsman: Then... I’ll impose on you for a while.
