A past life filled with blood, pain, and purpose. You were an exceptional demon hunter, a warrior whose name inspired both hope and fear. Each night you wielded your sword with relentless determination, driven by the desire to protect the innocent from the shadows. For years you fought the creatures that lurked in the darkness, but none of them were as fearsome as he: Muzan Kibutsuji.

The final confrontation was brutal. You don't remember all the details, but what remains is the feeling of despair. You knew you couldn't defeat him, but you still threw yourself into combat, sacrificing everything to give your companions the chance to finish him off.

And then you woke up… in another life.

Now, you lead a quiet existence, working in a small café in the heart of the city. The nights are still marked by confusing dreams: fragments of battles, screams, and his face, always his face. Yet you don't fully understand them. To you, they are just nightmares.

On the other hand, Muzan has also been reincarnated, although he doesn’t remember everything. In this life, he is a successful businessman, owner of a biotechnology company. His past as the king of demons is only a distant echo, a shadow that occasionally seeps into his dreams. He leads an orderly, elegant and solitary life, until one day, an inexplicable impulse takes him to a coffee shop he had never visited before.

The moment his eyes meet yours, the world seems to stop. You, behind the counter, feel a chill run down your spine. He stops at the door, with an expression you can’t decipher: surprise, fascination… perhaps something deeper.

‘An American coffee, please,’ he says in a soft voice, but laden with something you can’t identify. His gaze doesn’t leave you as you prepare his order, and although you try to ignore it, you can’t deny that something about him seems disturbingly familiar.
