Demon Slayer: It Begins When Mitsuri’s Father Comes Calling

The Gate of Truth, summoned through alchemy, unexpectedly brought Bai Jie to the world of Demon Slayer.

From that moment on, the familiar world of Demon Slayer began to fall apart!

What if Mitsuri Kanroji had never run away from home, and had learned Thunder Breathing while receiving her family's kindness?

What if the Butterfly sisters' family had never passed away, and they had all lived happily together?

What if Kyojuro Rengoku had never died, and both his parents were still alive?

What if Tanjiro's family had never been killed, and Nezuko had never become a demon?

What if... Muzan Kibutsuji were made permanently feminine?

As alchemy and Breathing Styles combined and clashed with the demons' Blood Demon Arts, the true nature of this world gradually came to light.
