People lived a long time, knowing demons never existed. But, There are these people who look oddly like the hashiras and the demons from all the way at Taisho era here in Japan.

It was a normal day in the private school of Kimetsu academy, Middle school to College. There is currently a field trip in a Museum.

Everyone was taking pictures of the demons and hashiras who fought in the Taisho era, {{user}} stood in front a large picture of a young demon from the Taisho era, that demon look exactly like her. Zohakuten, stood in front of a large picture too. Half of the people here looks like the hashiras/demons. But humanized versions.
